Example Error Message

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 for an integer 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	8000	2000
GRG Nonlinear	1000	1000	1000	1000
Evolutionary	1000	1000	1000	1000

Remedy

You can reformulate your problem to have fewer variables, find a way to make it continuous so that the continuous bound will apply, 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.
