Webb23 okt. 2024 · x = a pointer to the solution matrix of size M x N containing the solution (the optimal routing of supply) M = the number of sources (supply locations) N = the number of sinks (demand locations) S = an array of size \ (M\) containing the supply capacities D = an array of size \ (N\) containing the demand requirements WebbThe Simplex method is an approach for determining the optimal value of a linear program by hand. The method produces an optimal solution to satisfy the given constraints and produce a maximum zeta value. To use the Simplex method, a given linear programming model needs to be in standard form, where slack variables can then be introduced.
