Cause

The Solver engines that come built-in with Analytica Optimizer have limits on the number of variables and constraints that can appear in a single optimization problem. You've exceeded the maximum number of variables or constraints for a continuous optimization problem.

Engine Continuous Optimization (Mixed) Integer Optimization
Max Variables Max Constraints Max Variables Max Constraints
LP/Quadratic 8000 8000 2000 8000
SOCP Barrier 2000 2000 2000 2000
GRG Nonlinear 1000 1000 1000 1000
Evolutionary 1000 1000 1000 1000

Remedy

You can reformulate your problem to have fewer variables (or constraints) or you can purchase and use an add-on engine. The add-on engines do not have this limit (except for one, the LSGRG engine, which has a limit of 12,000 variables and 12,000 constraints). For a list of the available add-on engines and pricing see Powerful solver engines available for Optimizer.

This message is actually a warning, but if you ignore the warning, your solution will be Null, and the status will contain this message.
