Tree structure for DFS & BFS.

Example using 3 robots (X), 2 tasks (O) with cost from each robot to each task.

Results for best 1-swap:

Results for best k-swap using tree structure:

Example using recursive k-swap for grid implementation with (x, y) coordinates.

Tree class.

The tree class builds a tree of nodes. Each node consists of a task assignment configuration, including its makespan and sum of costs. Additionally, the node dynamically allocates new memory to create a layer of children nodes, pointing to their respective addresses in memory. Each layer of the tree represents the depth in which we do k-swaps. The explored task assignment configuration is stored in a hash table to prevent duplicates and allowing the algorithm to terminate.

The goal is to form a DFS/BFS heuristic using a mathematical hypothesis that hints at us in approaching a lower bound on makespan. The first step is to use a brute-force approach to keep track of the minimum makespan as we traverse the tree.
