Read data from .txt file
Hello! Is there a way to read data from a .txt file, without having to transform such file into GAMS sintaxis? For example, I want to read this instance of a scheduling problem *********************** 120 300 11 20 18 4 15 200 1000 2000 83 2 5 16 11 8 7 34 5 11 200 1000 2000 37 2 5 10 7 5 4 17 6 11 ...

Plot a rectangle
Dear all: I want to graphically represent a solution to a model, which can be done by means of rectangles. I have tried to find information about this, but what I found did not really help me. Even I found a related topic in this forum, but apparently it was too old and I could not access it. Any hi...

Re: set starting in 0
Thanks! I guess then that the second code I put
set j jobs /0*4/;
set i machine /1*2/;
is correct because the unique element list is 0,1,2,3,4.
I really appreciate the explanation
set j jobs /0*4/;
set i machine /1*2/;
is correct because the unique element list is 0,1,2,3,4.

set starting in 0
Hello! I found this week an error which I had never found before ... When running these lines *************** set i machine /1*2/; set j jobs /0*4/; parameter oo(j); oo(j) = ord(j); display oo; *************** I get an error. However, if I swap the first two, there is no error: ***************** set...

Re: Requesting Examples Branch-and-Check algorithm
Thanks Michael, I'll have a careful look at Erwin's B&B code, which surely will help me build my Branch-and-Check

Requesting Examples Branch-and-Check algorithm
Hello everyone!
I would like to code a Branch-and-Check algorithm in GAMS. Do you have an example you could share with me? This would be of great help
Thanks!

Re: print in excel parameter without domain index
Thanks Renger. I'll try that or, the easier brute force: define one scalar for each index value

print in excel parameter without domain index
Hello, I am trying to print in an excel sheet the values of a certain parameter, but I don't want for the domain set to be printed as well. For example, if I run: execute_unload 'results.gdx' x_model $onecho > gdxxrw_args_100.txt par=x_model rng=RCG_results!a1 $offecho execute 'gdxxrw.exe results.gd...
