Anyone can help

GAMS
1

Dear friends,

I would like to write two consecutive model A and model B, meaning
that solving model B has to use the results coming out from model A.
And now model A is sure to be correct and I am focusing on modifying
model B.

Is there any command in gams that I don’t have to run model A
everytime when I modify model B ? Because the results from model A is
always the same. It is quite annoying that everytime when I run model
B, the model A has to be run first and it taks long time.


Thank you very much in advance.
Jens

Jens,

I would use the save and restart feature of GAMS. Essentially, you
can split a .gms file in two pieces, A.gms and B.gms, and run it like
this:

gams A.gms save=A
gams B.gms restart=A
