Nettet6. jan. 2024 · If you do try my original solution, using the non-linear constraints, I suggest modifying the initial guess so that it satisfies, the equality constraint, e.g. x = [1/4,1/4,1/4,1/4]. I noticed that using your initial guess, the solution seems to terminate prematurely, with a function value that is larger than actual optimum. NettetWhat Are Linear Constraints? Several optimization solvers accept linear constraints, which are restrictions on the solution x to satisfy linear equalities or inequalities. Solvers that accept linear constraints include fmincon, intlinprog, linprog, lsqlin, quadprog, …
