stzLinearSolver

55 own methods · 0 forms written with extensions, listed under their method

the source: base/stats/stzLinearSolver.ring(opens in a new tab) · All classes · The area reference: Statistics & data-viz

Under each method, its extensions (Q CS XT Z ZZ IB W U): bold and ticked, it exists; struck, it does not. The extensions and what they mean

Examples: 0 come from the library's tests; 15 were composed from each method's signature and run for this page, on a fresh object, for example o1 = new stzLinearSolver() o1.AddIntegerVariable("x", 0, 100) o1.AddIntegerVariable("y", 0, 100) o1.AddConstraint("2*x + y", "<=", 100) o1.Maximize("3*x + 2*y"). 40 methods have none yet. Examples run on 2026-10-04 07:31 inside the library at commit 0e72e2e2c.
