Esteemed Advisers:
I'm looking for advice on how to improve the performance of my Proc Optmodel code. The present code takes about 37 minutes to solve. I've attached the relevant portions of the log file below.
The purpose of the code is to optimize the orientation of 8 cameras so as to maximize 3-camera coverage over the largest possible area. Each camera has 8 possible orientations. The spatial coverage of each orientation of each camera is represented by a binary coverage matrix on a 3-D Cartesian grid.
Currently, there are 12.5 million observations in coverage matrix and perhaps that's contributing to the slow execution times. I could reduce this number significantly by reducing the spatial resolution of the Cartesian Grid but I am reluctant to take this step at this time.
The orientation of one of the cameras is fixed and not subject to optimization but, not knowing how else to deal with this camera, I just assigned the identical binary coverage matrix to each orientation so, for this camera, all orientations have the same identical coverage. Perhaps there's a more efficient way to handle this circumstance.
As always, any suggestions or advice is greatly appreciated.
Regards,
Gene

For the station with a fixed orientation, you are introducing symmetry, which is usually bad news for a MILP solver. I recommend using a FIX statement to fix the CHI[station,a,e] variable to 1 for that specific <station,a,e>. Please rerun and show the new log.

Thanks, Rob, for your prompt response. I implemented your suggestion (correctly, I hope) but a NOTE (at line131): indicates that "Constraint CHI_constraint[USL000] causes the problem to be infeasible. The MILP presolver found this problem to be infeasible." The logfile is below.
Thanks for taking a look at this,

You should be fixing that station USL000 to only one orientation (one FIX statement). What you tried violates the CHI_constraint for that station.

Thanks, Rob, for pointing out my error. I fixed it and ran the code. Execution time was only a few seconds faster at 37 minutes and 10 seconds. The logfile is below. Do you see anything else that can be improved for better performance? Can you explain is happening under the hood when the Best Bound value creeps down at such small increments and so slowly?
Thanks for your help,
Gene

OK, it looks like the MILP presolver was already doing something like the fixing of that variable. In both cases, you get:
NOTE: The presolved problem has 2612 variables, 2579 constraints, and 35204 constraint coefficients.The small changes in the BestBound value are typical of the branch-and-cut algorithm, which improves the linear programming bound by branching and adding cutting planes.
The MILP solver also has a decomposition algorithm that can sometimes yield dramatic performance improvements over branch-and-cut. The simplest invocation involves just adding the DECOMP keyword to the SOLVE WITH MILP statement options.
If you can provide the code and data, I'll see if I can recommend anything else.

Rob,
I tried the DECOMP option but it didn't help. I can post the code here but what's the best way for me to send the dataset to you? It has 4.25 million observations and is 200MB.
Thanks for your offer to help,
Gene

For the RoO_Matrix data set, only the nonzero observations are needed.

Rob,
The dataset of non-zero observations is 950,000 observations and 44MB. Much larger than the 5MB attachment limit. Is there another way to send it to you?

I will have Technical Support contact you with instructions for sending the data sets.
