Hello

i am trying to get the time opl need to find each solution for my model in (C++) so i used

opl.getCP().ElapsedTime but it gives me with all solutions 34

and when i tried to get the total time needed to solve the problem i used :
opl.getCP().SolveTime but it gives me 1001 with all solutions

knowing that the model run in opl and fid a solution ( according to the side timer) in 00:01:55:16

and the timer for each of the two solution is :

610.55s
653.48s

can some-one help me explaining these numbers

Thanks

Hi,

This is indeed very strange and I'd like more information.
What version of CPLEX studio do you use?
Could you please provide the script & model that you use to get these results, I'd like to reproduce the symptoms that you have.
Thank you in advance.

Dear UMQX_Olfat_ELMahi ,

Please just post the code where you get and print the time information.
The problem might be there.

Hello,

Accessing informations about the state of the solver can be achieved by passing the info identifier (in your case MemoryUsage and ElapsedTime) to IloCP::getInfo(...). Right now, your code prints the integer value of the info identifier (which is naturally a constant).
So if you need to access the elapsed time, please use:

cp.getInfo(IloCP::ElapsedTime)

I hope this helps.

Hello

using : cp.getInfo(IloCP::ElapsedTime)

gives me the following errors:

can you help ?
Thanks

Dear UMQX_Olfat_ELMahi,

This error is due to the fact that you use a CPO parameter enum value instead of an info value.
Indeed,

IloCP::ElapsedTime

is one possible value of the

IloCP::TimeMode

parameter. What you should use is

cp.getInfo(IloCP::SolveTime)

.

Cordially,
Renaud
