hello,
In GAMS model, can I use 'if' statement in any constraint. Please tell me it is possible or not. If yes then please tell me syntax of that.
Thanks
if statement with constarints Topic is solved
Re: if statement with constarints
Hi
You can't use if-constructs in constraints, but you can use the $-operator (see the manual for more information) in your constraints if the condition relates to a parameter (not to a variable):
This works
Cheers

Code: Select all
parameter
p(t);
variable E(t), A(t), B(t);
myeq..
E(t) =E= A(t)$(p(t)>0) + B(t)$(p(t) < 0);

algorithm error
Hi,
Could anyone tell what this error means, apparently syntax for calling algorithm seems correct and as follow
OPTION MINLP = LMLBOA ;
while error massage is attached in attachment, if more information is required to understand error please let me know.
