Capstone Project with GAMS

<r><br/> I need to help to write the objective function. Our project topic is daily menu planning in our university restaurant and we are using gams but we couldnot write the objective function.<br/> We are using MIP in our model and the model should create a daily menu comprises from 5 different di...

Re: Nash-Cournot(mcp) to Stackelber(mpec), same output.

<t><br/> Attached is a modified version of your model that uses the GAMS EMP framework for solving<br/> these models. I believe this makes the model much easier to understand.<br/> <br/> The only issue is the definition of revenue which is the integral of the inverse demand.<br/> That gives the slig...

Nash-Cournot(mcp) to Stackelber(mpec), same output.

<r><br/> Hey. <br/> <br/> My Nash-Cournot (mcp) and Stackelberg (mpec) gives the same output. This is definitely wrong. <br/> Both models have the same constraints and parameters. <br/> <br/> In the Stackelberg model the profit-function is the object-function. <br/> The KKT-conditons from the Nash-C...
