Optquest running time

We want to know more about how Optquest works. Does it speed up the simulation in some way (say by suspending animation or unnecessary book keeping, etc )? Does it run simulations in parallel?

We need to optimize around 500-600 assignments and although I don't have it modeled yet, I am estimating each simulation run will take between 5-10 mins.

We might be able to put some constraints in there and try to group the variables into buckets, so that the number of assignments are reduced.

Software Version:

FlexSim 17.2.2

@Majid A,

Optimization instances are run in background processes (no graphics) at max speed.

The optimizer will launch as many simultaneous instances as your computer has cores. So if you have a quad-core CPU, 4 instances will run in parallel. If your CPU is Hyper-Threaded, it will run 8 instances at once, etc.
