Questions of using complementarity.jl to build the computable general equilibrium model #68

Closed KennethAnn closed 1 year ago

KennethAnn commented 1 year ago

Dear Professor Kwon, I am now using complementarity.jl to build a computable general equilibrium (CGE) model, which is in general established in GAMS software. A question is whether the NLconstraint can be used in MCPModel(), since I want to combine the nonlinear equations and MCP structure together.

@mapping is just an alias of @NLexpression. You can use nonlinear terms in @mapping. You cannot use @NLconstraint.

Thanks. I am curious about the model structure interface whether it could print the real value of each @mapping when I print the model. To do so, I can directly obtain the value of subexpressions, which could be benefit for checking the balance of equations. image
