Storing Sets as table entries

Hi all, I want to store all pair shortest paths. But I want to store the shortest path instead of the values of the shortest path between any two nodes. For example: I want to store the shortest path between node A and B that is A-C-D-E-B not the summation of edge weights of the path. I am unable to...

Non-Binary values taken by binary variables in GAMS/LINDO

Hi experts, I am new to GAMS and modelling a stochastic optimization problem using GAMS/LINDO. In the output returned by the solver, the variables I declared as binary are taking real values between 0 and 1 (eg. 0.66). Can someone please explain to me the scenario in the context of GAMS/LINDO. Follo...

Related to GAMS-LINDO for stochastic programs

Hi experts, I was trying to formulate a stochastic programs in GAMS with LINDO as a solver. It gave me licensing error while executing a relatively large model. Now I have installed LINDO full version on my windows machine but unable to find how to specify the path to my lindo installation in GAMS. ...

Lindo error in stochastic programming

Hi experts, I am new to stochastic programming and GAMS. While executing the GAMS file for stochastic programming I got following errors through emp file. **** SOLVER STATUS FILE LISTED BELOW =C*** emp.info line 3: Cannot find random parameter "=" in model. =C Hint: EMP keys like Chance, S...
