Advanced Topic 39 of 51 Math for Computing
Simplex Method
Classic algorithm for linear programs.
How it works
Moves from vertex to adjacent vertex of the feasible polytope improving the objective until optimal; worst case exponential but typically fast; interior-point methods are polynomial.
Where it is used
Solvers like CPLEX and GLPK.
Common pitfall
Degeneracy can cause cycling; use Bland's rule.
Where it fits in the course
Simplex Method is topic 39 of 51 in Math for Computing, rated Advanced. It follows Linear Programming. The next topic is Numerical Methods.
