Class Simplex

java.lang.Object

Simplex

public class Simplex
extends java.lang.Object

Compilation: javac Simplex.java Execution: java Simplex Given an M-by-N matrix A, an M-length vector b, and an N-length vector c, solve the LP { max cx : Ax <= b, x >= 0 }. Assumes that b >= 0 so that x = 0 is a basic feasible solution. Creates an (M+1)-by-(N+M+1) simplex tableaux with the RHS in column M+N, the objective function in row M, and slack variables in columns M through M+N-1.
