97774761-c0820b80-1b6f-11eb-895a-caf965e418c7 hi i saw pymoo and i think its amazing very tnx but i wanna know is it possible to solve a mixed integer programming (mip) in pymoo with pso ? and can u say please how is implementation of these constraints in pymoo? i have more than 20 constraints but with implement these three i can learn its pattern tnx. T : positive real variable q(i,j,g) : positive real variable D(i,j,g) : binary variable X(i,j,i',j',g): binary variable A(i,j,g) : binary variable W(i,j,g) : positive real variable S(i,j,g) : integer variable B : parameter M : bigM(parameter) i & i' = [1,2,3] j & j' = [1,2,3] g = [1,2]

Hi,

I haven't tested PSO with pymoo and I don't know if it can be used to solve MIP problems. I would ask them directly, I don't work with them. You can learn how to create a custom problem and how to define constraints here.
