Learn about vigilant mode.

First substantial release of SIROM as a deployable, documented service.

Highlights

  • HTTP API — async job API (POST /solve → poll GET /jobs/{id}) with a self-documenting Swagger /docs and a ready-to-run /example.
  • Deploy in one command — multi-stage Docker image + docker compose up; Redis-backed job store for multi-worker scale-out.
  • ~9–29× faster — GLOP auto-selection, vectorized quality measure + scenario generation, numpy solver build, and threaded scenario solves. See benchmarks/.
  • LP and MILP — integer variables supported; solver auto-selection (GLOP/SCIP) with overrides for CLP, PDLP, and commercial GUROBI/CPLEX/XPRESS.
  • Correctness — fixed the constraint-slack used for clustering; characterized its frontier impact across size/seed/structure (benchmarks/slack_fix_frontier.md).
  • Tooling & docs — per-phase benchmark harness, reusable frontier-diff tool, adoption-focused README with a frontier plot, CONTRIBUTING.md.
  • Demo — a polished robust investment-portfolio web app built on SIROM (demo/).

Implements the method from Butkeraites, de Salles Neto & Gendreau, Expert Systems with Applications 203:117337 (2022).
