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)

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(

Search and Problem Solving in AI

1. Define AI

Artificial Intelligence (AI) is the branch of computer science that develops machines capable of performing tasks that normally require human intelligence.

2. What is an Intelligent Agent?

An Intelligent Agent is an entity that perceives its environment through sensors and acts upon it using actuators to achieve goals.

3. Define a Problem-Solving Agent.

A Problem-Solving Agent is an intelligent agent that finds a sequence of actions to reach a goal from an
