The cargo loading problem essentially combines elements of both knapsack and bin packing problems, with broad practical applications. Cargo loading optimization involves maximizing utilization of transportation vehicles' (primarily trucks in this context) weight capacity and volume through advanced loading methods and strategic arrangement of cargo loading sequences. This approach minimizes distribution costs by fully leveraging the truck's volumetric and weight-bearing capabilities.

0-1 integer programming has broad applications in assignment problems, knapsack problems, and even TSP problems - all belonging to NP-hard class where exhaustive search becomes infeasible for large-scale instances. This implementation demonstrates a recursive approach to systematically enumerate all possible solutions for verification purposes, with a notable discrepancy found when comparing results against textbook examples.

The Knapsack Problem is a classic combinatorial optimization challenge: given a set of items with individual weights and values, determine the optimal selection of items to include in a knapsack such that the total weight does not exceed a specified limit while maximizing the total value. This problem derives its name from the scenario of filling a fixed-capacity backpack with the most valuable items possible. Implementation typically involves dynamic programming or heuristic algorithms like Particle Swarm Optimization (PSO) for larger problem instances.
