OR-Library

Beasley's collection of standard operational-research test instances.

Also called: OR-Library · ORLib

The pioneering repository, started by Beasley (1990), that distributes standard operational-research test instances electronically. Beyond knapsack, bin packing, and cutting stock it hosts data for a wide range of problems — set covering, assignment, facility location, and more. It links as a benchmark of the 0/1 Knapsack Problem, but is more general and older than the C&P-specific libraries (BPPLIB, 2DPackLib), so it is kept at evidence grade B (community resource).

Claims & evidence

Every relationship is a claim with an evidence grade; applicable problem-to-problem relationships also carry an equivalence level. See the evidence policy.

A–X describes evidence reliability; E0–E4 describes mathematical similarity between problems. The two axes are independent.
