Lab overview and goals

The goal of the lab is develop and implement an approximation algorithm to solve a Bin Packing Problem: find a way to pack N items of diffrent fixed sizes into 3 bins with capacity B each. The algorithm should try to minimize the amount of unused bin space (or, equivalently, the total unpacked amount).

Example: given B=20 and items of sizes

12, 4, 8, 15, 9, 3, 1, 10

you can pack the bins as [12, 8], [1, 4, 15], and [9, 10], with the leftover item of size 3.

It is proven that to find the optimal solution, one needs to consider all possibilities of packing which is exponential in N. However, there are good approximation algorithms that find a solution close to optimal in times polynomial in N. Your goal is to develop such an approximation algorithm, implement it, test it, and analyze its efficiency.
