Optimizing Product Allocation to Baskets

ghz 8months ago ⋅ 124 views

I am currently facing a challenge in devising an algorithm that optimally solves the following task:

We have a set of products, each associated with specific baskets they can be placed into. For instance, a Kiwi can be allocated to basket 1 or 2, while a Banana can only be placed in basket 1, and so forth. The objective is to distribute these products among the baskets in such a way that the largest basket accommodates the maximum number of products.

Consider the following example:

Kiwi - 1, 2 Banana - 1 Apple - 1, 2 Pineapple - 1, 3 Coconut - 2, 3 Plum - 3

The optimized distribution involves segregating the products as follows: Kiwi, Banana, Apple and Pineapple are assigned to Basket 1, Coconut and Plum are designated to Basket 3.

In essence, the challenge is to develop an algorithm that efficiently optimizes the allocation of products to baskets, prioritizing the maximization of the product count within the largest basket.

Answers To solve this optimization problem efficiently, you can use a greedy algorithm approach. Here's a step-by-step algorithm to achieve the desired optimization:

  1. Initialize an empty dictionary or hashmap to store the baskets and the products allocated to each basket.
  2. Iterate through each product and assign it to the basket with the fewest number of products so far. If multiple baskets have the same number of products, choose the basket with the lowest index.
  3. Keep track of the count of products in each basket.
  4. After assigning all products to baskets, identify the basket with the maximum number of products.
  5. Reassign any products from other baskets to the basket with the maximum count to maximize the product count within the largest basket.

Here's a Python implementation of the algorithm:

def allocate_products(products):
    baskets = {}
    
    for product, basket_options in products.items():
        min_basket = min(baskets, key=lambda x: len(baskets.get(x, [])))
        if min_basket not in basket_options:
            min_basket = min(basket_options)
        baskets.setdefault(min_basket, []).append(product)
    
    max_basket = max(baskets, key=lambda x: len(baskets.get(x, [])))
    
    for basket, products in baskets.items():
        if basket != max_basket:
            baskets[max_basket].extend(products)
    
    return baskets

# Example products
products = {
    "Kiwi": [1, 2],
    "Banana": [1],
    "Apple": [1, 2],
    "Pineapple": [1, 3],
    "Coconut": [2, 3],
    "Plum": [3]
}

# Allocate products to baskets
result = allocate_products(products)

# Print the optimized distribution
for basket, products in result.items():
    print(f"Basket {basket}: {', '.join(products)}")

This algorithm efficiently allocates products to baskets, prioritizing the maximization of the product count within the largest basket.
