Please Help Explain: Optimization and "# of simulations"

Postby ecarlino » 06 Aug 2018

If i setup an optimization for 'exhaustive', once I start it running, the # of Simulations matches the # of combinations that it showed when it was setting the properties (ie range of input values).

However, if i do the exact same but run 'genetic', then the # of simulations is many Many MANY multiples of the # of combinations.

I have attached screenshots to show what I am talking about.
My computer is running Windows Server 2016 and I am running the latest version of Multicharts.
The computer has 4 CPUs, each has 12 'real' cores, for a total of 48 'real' cores.

Hello, ecarlino!

What you’re describing is the result of 2 bugs of MultiCharts 11 that were related to incorrect optimization parameters initialization. These bugs were fixed in MultiCharts 12 Release-Candidate. You can download it as Beta on this page and test it: https://www.multicharts.com/download/

You can also find more info about that in this forum thread viewtopic.php?t=51229

For your reference

For an incremental GA opimization..total sims should be:

initial population (96) + number of generations(2777) * number of logical processors assigned(48??) = 133392

wilkinsw - thanks for your reply (and you numerous posts elsewhere on the topic!)

i've read a few papers on GA - do you have any insight (quick and dirty 'cheats') for what works best for "init pop" and "#gens"
---do you find that Multicharts suggestions are close to ideal?
---any 'best practicies' for Multicharts based on #cores on the computer?
