I’m no expert, but couldn’t you:

 

1)    Design the Objective function for the maximum number of constraints

2)    Fix the non-variable variables using equal upper and lower bounds?

Subject: [NLopt-discuss] How to design objective function with 
nonconstantnumber of variables?

 

Hi, 
My objective function have a lot of variables, but the number of variables is 
not constant, 
for example, the nubmer of varibles is decide by the number of layers of films 
every time before optimization.
And some variables may be set to constant value or not, which is decide by the 
user,
for example, after several optimazitons, some varible was set to a constant 
value. but later, it may be set to varible again.
Is ther anyone meet this kind of problem?
How to design my objective function?
Thanks a lot!
