Hello,

In srtree.gms code, what the following highlighted statements mean?

$eval nnodes card(s)*(card(t)-1)

set n nodes / n0*n%nnodes% /;

Your kind help will be highly appreciated.

This evaluates the expression after nnodes and stores. gams replaces %nnodes% by this value everywhere it is in your code.You can find these tricks in mccarls extended user guide in your gams/docs directory or directly under help.

Hi Renger,

I also have a question regarding the same gams file “srtree”. After the dynamic set “nn” is initialized, this loop start to assign values to random variables.

"loop(s,
loop(t$(ord(t):

Hi Yalin

This would take a little bit more than just my usual 5 minutes.

I suggest you compare and draw the tree that is the result of this formulation and compare it to the manual/paper.

Cheers
