HiMCM 2020 · Problem set

The 2020 contest paired a classic multi-criteria decision problem (picking the best summer job offer) with a real conservation-finance problem (where to spend a fixed budget to preserve Florida's threatened plants).

Contest datesNovember 4 – November 17, 2020 (14-day window)
Participation~830 teams worldwide [illustrative]
Problem AThe Best Summer Job — rank multi-attribute job offers
Problem BFunding Biodiversity Conservation — allocate a budget across Florida plants

Why this pair is great for a first weekend. Problem A is one of the most approachable HiMCM problems ever — almost any team can write a defensible model in 24 hours. Use it for a calibration run. Problem B is harder: it forces you to think about scarcity, triage, and what "biodiversity" actually means as a number.

The two problems

Why this year is good practice

  • Problem A is the textbook MCDM warm-up. If you have never used AHP or TOPSIS, do this one first — it will make 2024-A and 2025-B feel familiar.
  • Problem B teaches portfolio thinking. Allocating $X across species is isomorphic to allocating capex across renewable projects — same math, different context.
  • Both reward a clean sensitivity story. Personal-weight ranges in A; species-priority weights in B.
