Hi,

Can anyone tell whether GAMS allows a bilevel problem where both the leader and follower are mixed integer type optimization problem. If yes, is there any specific solver that is required to solve this kind of problem?

Hi, I would like to draw your attention regarding the syntax of this given code regarding bilevel optimization: https://www.gams.com/latest/docs/UG_EMP_Bilevel.html#UG_EMP_Bilevel_Example1 Since there is only one variable x in this case which doesn't belong to the follower so writing it was easy but...

Thanks a lot.

Hi, I am a pretty new user of GAMS. Recently I have come across a code snippet which is follows: $IFI '%SUSD_TRAJECTORY_CHECK%' == YES Q_SU_PUMP_RAMPDOWN_TRAJECTORY0(CONVENTIONAL_STORAGE_GEN,INTERVAL)$(ORD(INTERVAL) EQ 1).. $IFI '%SUSD_TRAJECTORY_CHECK%' == YES STORAGEVALUE(CONVENTIONAL_STORAGE_GEN,...

Sorry I forgot to mention how those two parameters declared,

SET
INTERVAL
GEN
MG_GEN

PARAMETERS
PUMPING_ENFORCED_ON(GEN,INTERVAL)
PUMPING_ENFORCED_ON_MG(MG_GEN,INTERVAL)

Hi, I have two gdx files, and I want to load two different but similar parameters from those two files respectively. While one gets loaded nicely but other is encountering error 362 (saying values for domain 2 are unknown no checking possible). My syntax for loading the two parameters from two gdx f...

Sorry, I guess my example problem really didn't match like my original problem ( I cannot share the exact formulation since it's proprietary). But I guess, you can get it from the following description. Actually, I could have written the way you have shown but the problem is I need a fixed group of ...

For example as a part of an optimization problem I need to calculate the electricity generation cost from different types of plant by this formula : generation*fuel_price. But for different fuels the price varies so even though the variable generation's name is same but should be used with different...

Hi, Is there any way to use different indexing for same variable in the same script? The reason for trying this thing is that a variable behaves the same way but needs to be indexed differently to be used in different equations since the constraints are different for different components. Can anyone...

Hi , I am facing the same issues during compilation of my developed model I am getting the error message like this in the '.lst' file 523 GEN_BLOCK_SCHEDULE_MG.LO(MG_GEN,BLOCK,INTERVAL)$(ORD(BLOCK) GT 1) = 0; **** $352 **** 352 Set has not been initialized But I have declared the variable 'GEN_BLOCK...
