Re: Lognormal distribution

Hi Farzad, That’s a good (and common) question. The reason that you are seeing this difference is that in Crystal Ball, the ‘default’ lognormal

Lognormal distribution

Dear All, The fit distribution to my data is a lognormal with mean of 21.99 and standard dev. of 34.97. Crystal ball shows that the cumulative probability for

Huybert, We've been doing the first part of your response (i.e., running 50K, then plugging in the best solution as the starting point of a new 50K run), but

Re: Trouble extracting OptQuest data...

Hi Jeff, I would think that running 50K iterations with only 40 decision variable should be more than enough to achieve near optimal solutions. I'm not too

Re: Trouble extracting OptQuest data...

Hi Jeff, Getting more memory could indeed help. However, another simple option that you could try is to run the optimization for 50,000 iteration, and after it

Hi, I'm running a deterministic optimization through OptQuest that involves 3 objectives, 40 decision variables, and 2 constraints. The model works well if I
