Simplex method in prime how to use the constrains maximise s.t. constraints.

[Albert Chan]

Hi, Anthony The Koala

Although HP Prime Cas also has fMin, simplex method is not implemented (yet)
From help screen, it only have the form fMin(Expr, [Var]).

XCas fMin allow more options: fMin(expr, constraints, vars, init, epsilon, max_iterations)

About [x,y] guess = [99, 99], it is just some number in the feasible region.

XCas Manual Wrote:Although the initial point is required to be feasible, the algorithm will sometimes succeed
even with a poor choice of initial point. Note that the initial value of a variable must not be zero.
