An in-process scheduler for periodic jobs that uses the builder pattern for configuration. An open problem (as far as I know) in three-dimensional Game of Life is to construct a “glider gun” for a reasonable three-dimensional ruleset. Motivation: Some discussion and collaboration enhances your educational experience, but too much collaboration---in the extreme case, copying each other's solutions--- is unethical and detrimental, and also leave you ill-prepared for the exams, which count for 50% of the grade. The subproblem is then solved and if the reduced cost of the solution is negative, the column is added to the RMP and the cycle continues until the reduced cost is.
