The included source code implements a variation of the Graph Coloring decision problem, as described in the included problem description text file. The algorithm implemented searches a “Zykov tree”, which computes the chromatic number of a graph by a recursive recurrence relation (as shown in the write-up). Each subexpression in the relation can be used to find a graph coloring of modified graphs. The concept of vertices that dominate other vertices in the graph helps drives the search through the recurrence relation. The parallelization was done with Cilk++.

The included source code finds a Maximum Independent Set (MIS) of a given graph, as described in the included problem description text file. The solution uses a modification to a max-clique algorithm found in a code library from University of Jilin, China. The algorithm uses a depth-first search component. This part of the algorithm is parallelized by assigning several recursive calls to the depth-first code on threads. The code is parallelized using Windows Threads.

The included source code implements a variation of the Hamiltonian Path problem, called the Travelling Baseball Fan Problem, as described in the included problem description text file. The serial algorithm is a recursive search of all potential paths. The parallelization was done with Intel Threading Building Blocks (TBB). Continuation tasks are set up for each tour day and parallel searches are executed within each new start day for the recursive algorithm to a given task generation depth. If there is no schedule for a day, the task for the next day is begun.
