Hi,

I have a very simple problem.

i am trying to calculate M[i][j] for all i in Nodes and j in Nodes, so i wrote the following to the .mod file;

float MNodesNodes;
execute {
for (var i in Nodes){
for (var j in Nodes) {
M[i][j]=theta*gamma+theta*sum(s in Nodes)g[s][j];
}
}
}

but it does not work. Any help?_

Hi,

it does not work because you should not use sum in the scripting part.
Sum should only be used in the OPL part
