CLUSTER LINEAR-INTERACTIVE-PROGRAMMING · 10 ENTRIES · EARLIEST ENTRY 2025-04-09

Interactive linear programming solvers

This cluster consists of web-based tools for solving linear programming problems, ranging from algorithm-specific demos (e.g., PDLP) to general solvers with GUI and 2D visualization of feasible regions. The cluster's dated history is too thin to read a shape from, as only one dated entry exists before the index start, and the remaining members predate the index or are undated. Among the members, linear-programming-solver leads on traction with 1 star, while others have none.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 10 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
