New to Analytica 4.3. Supercedes the earlier SolverInfo function.

OptEngineInfo(engine,item)

The SolverInfo function provides information about a specific optimizer engine, or about the solver engines that are currently installed and ready for use.

«Engine» is the name of a solver engine. The following are included with Analytica:

"Lp/Quadratic"
"SOCP Barrier"
"GRG Nonlinear"
"Evolutionary"

Various add-on engines can be purchased separately. These include:
