Optimization Techniques — Tabu Search
What is Tabu Search?
Tabu Search is a commonly used meta-heuristic used for optimizing model parameters. A meta-heuristic is a general strategy that is used to guide and control actual heuristics. Tabu Search is often regarded as integrating memory structures into local search strategies. As local search has a lot of limitations, Tabu Search is designed to combat a lot of those issues.
Tabu Search (TS)
The basic idea of Tabu Search is to penalize moves that take the solution into previously visited search spaces (also known as tabu). Tabu Search, however, does deterministically accept non-improving solutions in order to prevent getting stuck in local minimums.
Short-term vs. Long-term Memory
Short Term memory is based off of recency of occurrence and is used to prevent the search algorithm from revisiting previously visited solutions and also can be used to return to good components in order to localize and intensify a search. This is accomplished by the Tabu List and is also known as intensification.
Long Term memory is based off of frequency of occurrence and is used to diversity the search and explore unvisited areas of the search space by avoiding explored areas. This is accomplished by frequency memory and is also known as diversification.
Tabu List
The Tabu List is the cornerstone of utilizing short-term memory. This list stores a fixed amount of recently made moves. In some implementations, complete solutions are used instead of the moves used but this is not ideal if complete solutions are very large due to space limitations. Some examples of these moves are:
- swap nodes in a graph/tour
- toggling a bit between 0 and 1
- insert or delete edges in a graph

Tạo Bộ lọc Sản phẩm và Tìm kiếm Sử dụng HTML, CSS & Javascript
Chào mừng đến với hướng dẫn hôm nay. Trong hướng dẫn hôm nay, chúng ta sẽ học cách xây dựng bộ lọc và tìm kiếm sản phẩm. Để tạo dự án này, chúng ta cần HTML, CSS và Javascript. Vì đây là một dự án khá nâng cao, tôi sẽ không giới thiệu nó cho người mới bắt đầu sử dụng javascript. Nếu bạn là một trung cấp hoặc chuyên gia về javascript, bạn chắc chắn có thể tiếp tục và tạo ra cái này.
Hãy để chúng tôi có một cái nhìn tổng quan về dự án này thực sự là gì. Dự án bao gồm một loạt các thẻ sản phẩm. Mỗi thẻ này có tên, giá và danh mục được gán cho chúng. Phía trên các thẻ này, có một thanh tìm kiếm nơi người dùng có thể tìm kiếm một sản phẩm dựa trên tên của nó.
Bên dưới thanh tìm kiếm, có một nhóm các nút. Mỗi nút này có một tên danh mục trên đó. Khi người dùng nhấp vào bất kỳ nút nào trong số các nút này, các sản phẩm tương ứng với danh mục cụ thể đó sẽ được hiển thị.
Cấu trúc thư mục dự án:
Bây giờ trước tiên chúng ta hãy tạo cấu trúc thư mục dự án để chúng ta có thể bắt đầu viết mã. Chúng tôi bắt đầu bằng cách tạo một thư mục dự án có tên - 'Bộ lọc và Tìm kiếm Sản phẩm'. Bên trong thư mục này, chúng tôi tạo ba tệp. Đầu tiên là index.html, thứ hai là style.cssvà thứ ba là script.js. Các tệp này lần lượt là tài liệu HTML, biểu định kiểu và tệp tập lệnh.
HTML:
Chúng tôi bắt đầu với mã HTML. Trước tiên, hãy sao chép đoạn mã dưới đây và dán vào tệp HTML của bạn.

Создание фильтров поиска и товаров с помощью Javascript
Добро пожаловать в сегодняшнее руководство. В сегодняшнем руководстве мы узнаем, как создавать фильтры и искать товары. Для создания этого проекта нам понадобятся HTML, CSS и Javascript. Поскольку это довольно продвинутый проект, я бы не рекомендовал его новичку в javascript. Если вы средний уровень или эксперт в javascript, вы определенно можете сделать это.
Давайте посмотрим, что это за проект на самом деле. В проект входит серия карточек продуктов. У каждой из этих карт есть название, цена и категория. Над этими тегами находится панель поиска, где пользователи могут искать продукт по его названию.
Под панелью поиска находится группа кнопок. На каждой из этих кнопок есть название категории. Когда пользователь нажимает любую из этих кнопок, будут отображаться продукты, соответствующие этой конкретной категории.
Структура папок проекта:
Теперь давайте сначала создадим структуру каталогов проекта, чтобы мы могли начать кодирование. Начнем с создания папки проекта с названием «Фильтры и поиск продуктов». Внутри этой папки мы создаем три файла. Первый есть index.html, второй есть style.cssи третий есть script.js. Эти файлы представляют собой HTML-документы, таблицы стилей и файлы сценариев соответственно.
HTML:
Начнем с HTML-кода. Сначала скопируйте приведенный ниже код и вставьте его в свой HTML-файл.
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Product Filter And Search</title>
<!-- Google Font -->

</head>
<body>
<div class="wrapper">
<div id="search-container">
<input
type="search"
id="search-input"
placeholder="Search product name here.."
/>
<button id="search">Search</button>
</div>
<div id="buttons">
<button class="button-value" onclick="filterProduct('all')">All</button>
<button class="button-value" onclick="filterProduct('Topwear')">
Topwear
</button>
<button class="button-value" onclick="filterProduct('Bottomwear')">
Bottomwear
</button>
<button class="button-value" onclick="filterProduct('Jacket')">

</button>
<button class="button-value" onclick="filterProduct('Watch')">
Watch
</button>
</div>
<div id="products"></div>
</div>
<!-- Script -->
<script src="script.js"></script>
</body>
</html>CSS:
Далее, чтобы добавить стили в этот проект, мы используем CSS. Теперь скопируйте приведенный ниже код и вставьте его в свой файл CSS.

border-radius: 3em;
background-color: transparent;

}
.active {
background-color: #6759ff;
color: #ffffff;
}
#products {
display: grid;
grid-template-columns: auto auto auto;
grid-column-gap: 1.5em;
padding: 2em 0;
}
.card {
background-color: #ffffff;
max-width: 18em;
margin-top: 1em;
padding: 1em;
border-radius: 5px;

}
.container {

}
.container h5 {

}
.card {
max-width: 10em;
margin-top: 1em;
}
#products {
grid-template-columns: auto auto;
grid-column-gap: 1em;
}
}Javascript:
Наконец, нам нужно добавить функциональность к фильтру, а также реализовать функцию поиска. Чтобы он заработал, мы добавляем javascript. Скопируйте приведенный ниже код и вставьте его в свой файл javascript.

Cree filtros de búsqueda y de productos utilizando Javascript
Bienvenido al tutorial de hoy. En el tutorial de hoy, aprenderemos cómo crear filtros y buscar productos. Para crear este proyecto, necesitamos HTML, CSS y Javascript. Dado que este es un proyecto bastante avanzado, no se lo recomendaría a un principiante de JavaScript. Si eres un intermedio o un experto en javascript, definitivamente puedes seguir adelante y hacer este.
Tengamos una visión general de lo que realmente es este proyecto. El proyecto incluye una serie de fichas de producto. Cada una de estas tarjetas tiene asignado un nombre, precio y categoría. Por encima de estas etiquetas, hay una barra de búsqueda donde los usuarios pueden buscar un producto según su nombre.
Debajo de la barra de búsqueda, hay un grupo de botones. Cada uno de estos botones tiene un nombre de categoría. Cuando el usuario haga clic en cualquiera de estos botones, se mostrarán los productos correspondientes a esa categoría en particular.
Estructura de la carpeta del proyecto:
Ahora, primero creemos la estructura del directorio del proyecto para que podamos comenzar a codificar. Comenzamos creando una carpeta de proyecto llamada - 'Filtros y búsqueda de productos'. Dentro de esta carpeta creamos tres archivos. El primero es index.html, el segundo es style.cssy el tercero es script.js. Estos archivos son documentos HTML, hojas de estilo y archivos de script, respectivamente.
HTML:
Empezamos con el código HTML. Primero, copie el código a continuación y péguelo en su archivo HTML.
<!DOCTYPE html>

</button>
</div>
<div id="products"></div>
</div>

Créez des filtres de recherche et de produits à l'aide de Javascript
Bienvenue dans le tutoriel d'aujourd'hui. Dans le didacticiel d'aujourd'hui, nous allons apprendre à créer des filtres et à rechercher des produits. Pour créer ce projet, nous avons besoin de HTML, CSS et Javascript. Comme il s'agit d'un projet assez avancé, je ne le recommanderais pas à un débutant en javascript. Si vous êtes un intermédiaire ou un expert en javascript, vous pouvez certainement aller de l'avant et créer celui-ci.
Ayons un aperçu de ce qu'est réellement ce projet. Le projet comprend une série de fiches produits. Chacune de ces cartes a un nom, un prix et une catégorie qui leur sont attribués. Au-dessus de ces balises, il y a une barre de recherche où les utilisateurs peuvent rechercher un produit en fonction de son nom.
Sous la barre de recherche, il y a un groupe de boutons. Chacun de ces boutons a un nom de catégorie. Lorsque l'utilisateur clique sur l'un de ces boutons, les produits correspondant à cette catégorie particulière seront affichés.
Structure du dossier du projet :
Maintenant, créons d'abord la structure du répertoire du projet afin que nous puissions commencer à coder. Nous commençons par créer un dossier de projet nommé - « Filtres et recherche de produits ». Dans ce dossier, nous créons trois fichiers. Le premier est index.html, le second est style.csset le troisième est script.js. Ces fichiers sont respectivement des documents HTML, des feuilles de style et des fichiers de script.
HTML :
Nous commençons par le code HTML. Tout d'abord, copiez le code ci-dessous et collez-le dans votre fichier HTML.
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Product Filter And Search</title>
<!-- Google Font -->
<link
href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500&display=swap"
rel="stylesheet"
/>
<!-- Stylesheet -->
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="wrapper">
<div id="search-container">
<input
type="search"
id="search-input"
placeholder="Search product name here.."
/>
<button id="search">Search</button>
</div>
<div id="buttons">
<button class="button-value" onclick="filterProduct('all')">All</button>
<button class="button-value" onclick="filterProduct('Topwear')">
Topwear
</button>
<button class="button-value" onclick="filterProduct('Bottomwear')">
Bottomwear
</button>
<button class="button-value" onclick="filterProduct('Jacket')">
Jacket
</button>
<button class="button-value" onclick="filterProduct('Watch')">
Watch
</button>
</div>
<div id="products"></div>
</div>
<!-- Script -->
<script src="script.js"></script>
</body>
</html>CSS :
Ensuite, pour ajouter des styles à ce projet, nous utilisons CSS. Copiez maintenant le code ci-dessous et collez-le dans votre fichier CSS.

#search-container {
margin: 1em 0;
}
#search-container input {
background-color: transparent;

grid-template-columns: auto auto auto;
grid-column-gap: 1.5em;
padding: 2em 0;
}
.card {
background-color: #ffffff;
max-width: 18em;
margin-top: 1em;
padding: 1em;
border-radius: 5px;
box-shadow: 1em 2em 2.5em rgba(1, 2, 68, 0.08);
}
.image-container {
text-align: center;
}
img {
max-width: 100%;
object-fit: contain;
height: 15em;
}
.container {
padding-top: 1em;
color: #110f29;
}
.container h5 {
font-weight: 500;
}
.hide {
display: none;
}
@media screen and (max-width: 720px) {
img {
max-width: 100%;
object-fit: contain;
height: 10em;
}
.card {
max-width: 10em;
margin-top: 1em;
}
#products {
grid-template-columns: auto auto;
grid-column-gap: 1em;
}
}Javascript :
Enfin, nous devons ajouter des fonctionnalités au filtre et également implémenter la fonction de recherche. Pour que cela fonctionne, nous ajoutons javascript. Copiez le code ci-dessous et collez-le dans votre fichier javascript.

Crie filtros de pesquisa e de produto usando HTML, CSS e Javascript
Bem-vindo ao tutorial de hoje. No tutorial de hoje, aprenderemos como construir filtros e pesquisar produtos. Para criar este projeto, precisamos de HTML, CSS e Javascript. Como este é um projeto bastante avançado, eu não o recomendaria para um iniciante em javascript. Se você é um intermediário ou especialista em javascript, pode definitivamente ir em frente e fazer este.
Vamos ter uma visão geral do que esse projeto realmente é. O projeto inclui uma série de cartões de produtos. Cada um desses cartões tem um nome, preço e categoria atribuídos a eles. Acima dessas tags, há uma barra de pesquisa onde os usuários podem pesquisar um produto com base em seu nome.
Abaixo da barra de pesquisa, existe um grupo de botões. Cada um desses botões possui um nome de categoria. Quando o usuário clica em qualquer um desses botões, os produtos correspondentes a essa categoria específica serão exibidos.
Estrutura da pasta do projeto:
Agora vamos primeiro criar a estrutura do diretório do projeto para que possamos começar a codificar. Começamos criando uma pasta de projeto chamada - 'Filtros e Pesquisa de Produto'. Dentro desta pasta, criamos três arquivos. O primeiro é index.html, o segundo é style.csse o terceiro é script.js. Esses arquivos são documentos HTML, folhas de estilo e arquivos de script, respectivamente.
HTML:
Começamos com o código HTML. Primeiro, copie o código abaixo e cole em seu arquivo HTML.
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Product Filter And Search</title>
<!-- Google Font -->
<link
href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500&display=swap"
rel="stylesheet"
/>
<!-- Stylesheet -->
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="wrapper">
<div id="search-container">
<input
type="search"
id="search-input"
placeholder="Search product name here.."
/>
<button id="search">Search</button>
</div>
<div id="buttons">
<button class="button-value" onclick="filterProduct('all')">All</button>
<button class="button-value" onclick="filterProduct('Topwear')">
Topwear
</button>
<button class="button-value" onclick="filterProduct('Bottomwear')">
Bottomwear
</button>
<button class="button-value" onclick="filterProduct('Jacket')">
Jacket
</button>
<button class="button-value" onclick="filterProduct('Watch')">
Watch
</button>
</div>
<div id="products"></div>
</div>
<!-- Script -->
<script src="script.js"></script>
</body>
</html>CSS:
Em seguida, para adicionar estilos a este projeto, usamos CSS. Agora copie o código abaixo e cole-o em seu arquivo CSS.
* {
padding: 0;
margin: 0;
box-sizing: border-box;
border: none;
outline: none;
font-family: "Poppins", sans-serif;
}
body {
background-color: #f5f8ff;
}
.wrapper {
width: 95%;
margin: 0 auto;
}
#search-container {
margin: 1em 0;
}
#search-container input {
background-color: transparent;
width: 40%;
border-bottom: 2px solid #110f29;
padding: 1em 0.3em;
}
#search-container input:focus {
border-bottom-color: #6759ff;
}
#search-container button {
padding: 1em 2em;
margin-left: 1em;
background-color: #6759ff;
color: #ffffff;
border-radius: 5px;
margin-top: 0.5em;
}
.button-value {
border: 2px solid #6759ff;
padding: 1em 2.2em;
border-radius: 3em;
background-color: transparent;
color: #6759ff;
cursor: pointer;
}
.active {
background-color: #6759ff;
color: #ffffff;
}
#products {
display: grid;
grid-template-columns: auto auto auto;
grid-column-gap: 1.5em;
padding: 2em 0;
}
.card {
background-color: #ffffff;
max-width: 18em;
margin-top: 1em;
padding: 1em;
border-radius: 5px;
box-shadow: 1em 2em 2.5em rgba(1, 2, 68, 0.08);
}
.image-container {
text-align: center;
}
img {
max-width: 100%;
object-fit: contain;
height: 15em;
}
.container {
padding-top: 1em;
color: #110f29;
}
.container h5 {
font-weight: 500;
}
.hide {
display: none;
}
@media screen and (max-width: 720px) {
img {
max-width: 100%;
object-fit: contain;
height: 10em;
}
.card {
max-width: 10em;
margin-top: 1em;
}
#products {
grid-template-columns: auto auto;
grid-column-gap: 1em;
}
}Javascript:
Finalmente, precisamos adicionar funcionalidade ao filtro e também implementar a função de pesquisa. Para fazer funcionar, adicionamos javascript. Copie o código abaixo e cole em seu arquivo javascript.

name.innerText = i.productName.toUpperCase();
container.appendChild(name);
//price
let price = document.createElement("h6");
price.innerText = "$" + i.price;
container.appendChild(price);
card.appendChild(container);
document.getElementById("products").appendChild(card);
}
//parameter passed from button (Parameter same as category)
function filterProduct(value) {
//Button class code
let buttons = document.querySelectorAll(".button-value");
buttons.forEach((button) => {
//check if value equals innerText
if (value.toUpperCase() == button.innerText.toUpperCase()) {
button.classList.add("active");
} else {
button.classList.remove("active");
}
});
//select all cards
let elements = document.querySelectorAll(".card");
//loop through all cards
elements.forEach((element) => {
//display all cards on 'all' button click
if (value == "all") {

} else {
//hide other elements
element.classList.add("hide");
}
}
});
}
//Search button click
document.getElementById("search").addEventListener("click", () => {
//initializations
let searchInput = document.getElementById("search-input").value;
let elements = document.querySelectorAll(".product-name");
let cards = document.querySelectorAll(".card");
//loop through all elements
elements.forEach((element, index) => {
//check if text includes the search value
if (element.innerText.includes(searchInput.toUpperCase())) {
//display matching card
cards[index].classList.remove("hide");
} else {
//hide others
cards[index].classList.add("hide");
}
});
});
//Initially display all products
window.onload = () => {
filterProduct("all");
};Sua pesquisa e filtro de produto agora estão prontos. Espero que tenha gostado do tutorial.
