So for the XYZ problem, the initial basic feasible solution is (0,0,4,12,18). This gives us an objective function of zero, which is not very optimal, but at least it's a start.

Perold, André. "Extreme Points and Basic Feasible Solutions in Continuous Time Linear Programming." SIAM Journal on Control and Optimization 19, no. 1 (1981): 52–63.

An algorithm for ranking the basic feasible solutions corresponding to a linear programming problem in increasing order of the linear objective function is described. An application of this algorithm ...
