Please do you have the CPLEX studio 12.7 installer? I'm a student and I only need the installer for the enterprise 12.7 version (or 12.6.3) for 2 months, which allows me to support more than a thousand variables. Thank you very much

Hi, Stephen.

I have a question about cplex.

How can I delimit the execution time in cplex? for example, if I want the execution time stopping in 10 minutes.

Thanks.

hey stephen, im trying to solve a vehicle routing problem with using Cplex, i have implemented the mathematical model of VRP, but finaly i can't exucute my program because i face a special error, i have a constraint with a quadratic term ( the product of binary variable and bounded variable), the error says that Q is not positive semi definite, so it's been a long time that i struggle with this error, so if it is possible, i need some help ; thank you in advance
