Webb8 jan. 2024 · Often in physical science research, we end up with a hard problem of optimizing a function (called objective) that needs to satisfy a range of constraints — linear or non-linear equalities and inequalities. The optimizers usually also have to adhere to the upper and lower bound. WebbThe population size for ISRES defaults to 20× ( n +1) in n dimensions, but this can be changed with the nlopt_set_population function. This method supports arbitrary …

Webb19 apr. 2024 · The constraints are that the capacity of any grid cell is not violated. That is, the sum of weights of nodes in a grid cell does not exceed its capacity. I get an "nlopt invalid argument" error when I try to add the vector of inequality constraints with opt.add_inequality_mconstraint. My constraints are for each grid cell whose length is 6. Webb2 nov. 2024 · nonlinear inequality constraints (sometimes called a nonlinear programming problem), which can be speciﬁed in g(·), and equality constraints that can be speciﬁed in h(·).

Not all algorithms can handle inequality constraints, so we have to specify one that does, NLOPT_LD_MMA (Svanberg 2002). We also specify the option print_level to obtain output during the optimization process.
