Announcing LINDO API 15, the Solver Engine Callable Library

LINDO API 15 includes substantial improvements to all components of the library, the LP/MIP solvers, Global optimizer, Nonlinear solver, and has enhanced support for external MIP solvers. 

Details:

• Improved reproducibility when solving a problem repeatedly, particularly with the concurrent option choosing the fastest of Barrier, Primal simplex, and dual simplex.

• Global solver offers improved handling of IF statements and polynomials. 

• Recognizes the CENSOR( x, LB, UB) construct which is the simplest form of an S-curve function such as might be found in neural networks. 

• Recognizes the POLYNOMIAL construct to better exploit univariate polynomials.

• Improved Multi-start for quickly finding good solutions to difficult nonconvex problems,

• Increased support for external solvers, including linear solvers such as COPT, CLP, HIGHS,

• Improved support for some external Nonlinear solvers.

• LINDO API 15 is available on all major platforms: Windows, Linux, MacOS, ARM, Android.
