- Operations Research: An Introduction — Taha. For the optimization side (LP, IP, networks, queueing).
- The Elements of Statistical Learning — Hastie, Tibshirani, Friedman (free PDF online). Reference for regression, classification, sensitivity. Read selectively.
- How to Write Mathematics — Halmos / Steenrod (the AMS book). Tiny, classic, makes your writing better in an afternoon.

Writing & typesetting
- Overleaf — collaborative online LaTeX (free tier is enough).
- LaTeX docs.
- tex.stackexchange.com — for any specific problem.

Communities (during prep — not during the contest!)
- Art of Problem Solving forums (search "HiMCM").
- r/HighSchoolMath on Reddit — occasional HiMCM discussion.
- School math/CS clubs — find a former team member at your school.
During the contest window, all outside-team discussion is banned. Don't post on
Discord, Reddit, Stack Exchange, or anywhere else. COMAP monitors the web and has disqualified
teams for this.
Glossary
- AHP
- Analytic Hierarchy Process. Method for deriving criterion weights from pairwise comparisons.
- ARIMA
- AutoRegressive Integrated Moving Average. A flexible time-series forecasting model.
- Carrying capacity ($K$)
- The maximum sustainable size of a population given its environment. Appears in logistic growth.
- Compartmental model
- A model where the system is divided into discrete states (compartments) with flows between them (e.g., SIR).
- CWM
- Combined Weight Model. Common HiMCM approach: average AHP weights (subjective) with EWM weights (data-driven).
- EWM
- Entropy Weight Method. Computes weights based on the variation each criterion shows across alternatives.
- Finalist
- HiMCM award level. Papers that reach final judging (~5%). Above Meritorious, below Outstanding.
- Hectare
- 10,000 m². A 20-acre area is about 8.1 hectares.
- HiMCM
- High School Mathematical Contest in Modeling. The contest this whole site is for.
- IM²C
- International Mathematical Modeling Challenge. The international round held in spring; US teams qualify via Meritorious+ at HiMCM.
- IP / MIP
- Integer Programming / Mixed-Integer Programming. Optimization with discrete-valued variables.
- LP
- Linear Programming. Optimization with a linear objective and linear constraints.
- Markov chain
- A discrete-state stochastic process where the future depends only on the current state.
- Meritorious
- HiMCM award level. Excellent across modeling, analysis, and communication. Roughly the top 20% (Meritorious + Finalist + Outstanding).
- Monte Carlo
- Simulation method that draws random samples to estimate distributions of outputs.
- NCTM
- National Council of Teachers of Mathematics. Co-sponsors the NCTM Award given to selected HiMCM Outstanding teams.
- NPV
- Net Present Value. Sum of discounted future cash flows; central to financial models.
- ODE / PDE
- Ordinary / Partial Differential Equation. ODE = single independent variable (usually time); PDE = multiple (e.g., time and space).
- Outstanding
- The top HiMCM award (~1% of submissions).
- SDE
- In the 2024 problem, "Sport, Discipline, or Event" — not stochastic differential equation.
- Sensitivity analysis
- The process of measuring how a model's outputs depend on its inputs/parameters.
- TOPSIS
- Technique for Order of Preference by Similarity to Ideal Solution. Multi-criteria ranking method based on distance to ideal best/worst.
