LINGO 22, What'sBest! 20 and LINDO API 16 by LINDO Systems Inc., USA LINDO Systems supplies software for building and solving optimisation models: linear, nonlinear (convex and nonconvex/global), quadratic, conic, stochastic and integer. Typical applications are production planning, transport, finance, portfolio allocation, capital budgeting, blending, scheduling, inventory and resource allocation.

Products

• LINGO 22 Modelling language and solver environment. Models are written with sets and summations, data is read from and written to spreadsheets and databases, and the appropriate solver is selected automatically. LINGO can also be called from your own applications.

• What'sBest! 20 Optimisation add-in for Excel. Models are built directly in the spreadsheet, using normal Excel formulas.

• LINDO API 16 Solver library for embedding the LINDO solvers in your own applications. Runs natively on Apple M-series processors.

New in LINGO 22 and What'sBest! 20

• Faster linear solver Simplex performance on large models improved by 25-30% on average.

• Integer solver 20% more benchmark models solved to optimality within two hours, with new root-node heuristics and faster re-optimisation.

• Global solver Tighter bounds and linear relaxations, and better conversion of nonlinear models to equivalent linear models.

• External solvers Improved support for COPT, Coin/CLP and HiGHS.

• Time to best solution Reported in the solution and status reports.

• LINGO and Excel LINGO models can be run from Excel, and moved between Excel and the LINGO editor.

• LINGO in Visual Studio Code LINGO-LSP for editing and running models, and LINGO Copilot for generating LINGO code from a description in plain language or LaTeX.

• What'sBest! Excel functions Support for newer Excel functions such as NORM.DIST, BINOM.DIST, POISSON.DIST and LOGNORM.DIST.
