Realy thanks!

Hi Michael as always many thanks!

Hi all, Does anyone have an example of implementation of Heuristic Algorithm (e.g. GA or SA) in GAMS?

is it possible to run a GA or SA MATLAB code in GAMS code?
How to use meta heuristic (GA) MATLAB code in GAMS?



Many Thanks!

Hi all


I have binary parameter b(j) , j/1*100/ . I need to change the element of b (change 1 to 0 and 0 to 1 ) to get new parameter c(j). I want to use macro option, is it possible?
Thanks!

Hi Steve thanks a lot!

Hi all, I want to code the following formula in GAMS, R(i)= Phi.[beta*Log10(M(i)/W*D)] Where 'Phi' is a standard normal cumulative distribution function. Scalar beta=0.34, W=70, D=41; Parameter M(i)/1 375, 2 450, 3 876,4 212,5 125/; I didn't find standard normal cumulative distribution function in G...

Thanks so much !

Hi, let s be a index of scenario and j index of Network Nodes.(s={1*200} , j={1*100}) d(s,j)= total impacts of contamination scenario s, if the contaminant is first detected by scenario at j. W(s)=the subset of Network Nodes which d(s,j)<>0. W'(s)= the subset of W(s) such that d(s,j)<>d(s,j') , for ...

Ok , thanks.

Hi,

What is the meaning of this error?
When I receive this error, the program does not work anymore, And everything completely stops.

How can I fix this error?
