WebThe method used to solve Equation 5 differs from the unconstrained approach in two significant ways. First, an initial feasible point x0 is computed, using a sparse least-squares step, so that Ax0 = b . WebTheory and methods for linear programming is well-developed, and well understood. There are several software packages including open-source or commercial to solve linear programs. Two well-known methods for LPs are the simplex method invented by G. B. Dantzig in 1947 and the interior-point method (I.I. Dikin (1967), N. Karmarkar (1984)). microgreen germination trays
