1. Understanding AI: Thought Process and Behavior

Artificial Intelligence (AI) can be understood based on thought process and behavior in four ways:

Thinking Humanly: AI tries to think like a human being. Example: A chatbot understanding a user’s question and giving a human-like response.
Thinking Rationally: AI uses logical reasoning to reach a conclusion. Example: An expert system using medical rules to identify a disease.
Acting Humanly: AI performs actions similar to humans. Example: A humanoid

Posted by admin on Jul 29, 2026 in Computer Engineering | 0 comments

Food Delivery Order Management System

This implementation focuses on the OrderManager class to handle various aspects of a food delivery service, including statistics, fee calculation, and partner recommendations.

Order Statistics in OrderManager

Implementing getOrderStatistics

The following method calculates the total, active, and closed orders within the system.

OrderStats getOrderStatistics() {
    int total = orders.size();
    int active = 0;
    int closed = 0;

    for (Order order : orders) {

Electric Field Intensity for Point and Line Charge Distributions

k = 9 * 10**9
print("1. Point Charge")
print("2. Line Charge")
ch = int(input("Enter choice: "))
if ch == 1:
    q = float(input("Enter charge (C): "))
    x = float(input("Enter x coordinate: "))
    y = float(input("Enter y coordinate: "))
    z = float(input("Enter z coordinate: "))
    r = (x**2 + y**2 + z**2)**0.5
    if r == 0:
        print("Distance cannot be zero")
    else:
        E = k * q / (r**2)
        print("Electric

Artificial Intelligence Search and Knowledge Systems

Heuristic Search and Hill Climbing Algorithms

A Heuristic Search is a search technique that uses heuristic information (rules or estimates) to find a solution faster than uninformed search methods.

A heuristic function is written as: h(n) = Estimated cost from node n to the goal.

Hill Climbing is a heuristic search algorithm that continuously moves toward the neighboring state with the highest value (better solution) until no better neighbor exists.

It is called “hill climbing” because it always tries

Patrones de Diseño Creacionales

Singleton

Propósito: Evitar instancias duplicadas.

public class S
{
    private static S _i;
    private S() { }
    public static S Instance
    {
        get
        {
            if (_i == null) _i = new S();
            return _i;
        }
    }
}

Factory Method

Propósito: Uso de if/else para crear objetos.

public abstract class C
{
    public P Crear(string t)
    {
        var p = CrearP(t);
        p.Init();
        return p;
    }
    protected abstract P CrearP(
