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? __________________________________________________________________________________________ Anthony Waters ● Senior Staff Consultant ● KBC Process Technology Ltd T 44 (0)1606 815100 ● Direct +44 (0)1606 815182 ● F +44 (0)1606 815151 [email protected] <mailto:[email protected]> From: [email protected] [mailto:[email protected]] On Behalf Of King Simon Sent: 16 January 2011 10:39 To: [email protected] 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! This e-mail is confidential and intended only for the individual(s) to whom it is addressed.
