Description
Pham Thanh Hieu and Nguyen Kieu Linh present a benchmark data set built from world trade records in a 2026 data article. Trade webs settle into balance states that math models frame as inequality puzzles, yet test sets for solver tools were scarce. A pipeline turns product level trade files into clean puzzle cases with known trade flows as ground truth.
Source files cover yearly flows among lands for 2017 to 2024 at fine product detail. Steps filter live flows, group products into five sectors, pick lead trade lands, and tune a cost and price rule to match real flows. Cases ship in two sizes with feasible sets, tuned rules, flow tables, and check scores, plus solver test results and build scripts for reuse.
