Operations Research Exhibit and Presentation Standards

v20260724
ors-tables-figures
A comprehensive guide for constructing rigorous and structured exhibits (tables, figures, theorems) for Operations Research (OR) manuscripts, adhering to INFORMS house style. It details requirements for formal statement layout, comparison tables against prior work, computational results, and performance plots, ensuring maximum academic rigor and reproducibility.

Overview

Tables, Figures & Exhibits (ors-tables-figures)

When to trigger

  • The model, proofs, and computational results exist and must be displayed clearly.
  • You need a clean comparison table separating your method from prior work.
  • Reviewers should be able to read a result table without hunting through the text.

Exhibits that carry an OR paper

Unlike empirical social-science papers built around correlation and regression tables, Operations Research exhibits are about structure, guarantees, and computation:

  • Formal-statement layout: number theorems, propositions, lemmas, and assumptions consistently (Theorem 1, Assumption 1) and reference them by number everywhere. Use the INFORMS LaTeX style files / amsthm so environments render uniformly.
  • Comparison table (prior work × properties): rows = methods/papers, columns = {assumptions, strongest result, approximation factor, complexity/rate}. This is the single most persuasive OR exhibit for novelty.
  • Computational-results table: instances/sizes × {optimality gap, time, iterations, baseline comparison}. Report units, time limits, and which configuration produced the row; bold or mark wins honestly.
  • Plots: convergence curves, scaling (size vs. time, ideally log-log), performance profiles across instance sets, and for stochastic output error bars / confidence intervals — never bare means.

INFORMS house-style notes

  • Format: prepare for 1.5-spaced, 11-point, 1-inch-margin manuscript layout; submit as PDF (source LaTeX/Word on acceptance). Use the provided LaTeX style files.
  • Self-contained exhibits: each table/figure has a complete caption (what, units, instance set, what "best" means) so it stands alone.
  • Notation consistency: symbols in exhibits match the text exactly; define them in the caption or a notation table.
  • E-companion: large result tables and ablations can go to the e-companion (which must not be longer than the manuscript); keep the headline exhibits in the main text.

Vector tooling

Use TikZ/PGFPlots (or matplotlib exported to vector) for crisp figures; performance profiles and log-log scaling plots reproduce well as vectors. Keep raw data/scripts in the ORJournal repository so every exhibit regenerates.

Exhibit pushback patterns and the INFORMS-style fix

Referee remark on an exhibit What it flags Venue-specific fix
"Computational study lacks benchmarks" no recognized baseline column add a column for the closest prior method and a strong solver on standard instances
"Cannot tell what 'best' means" undefined win marking caption defines the metric and tie-breaking; bold/mark honestly
"Results not reproducible from the table" missing units/time-limit/hardware state units, time limit, termination, hardware, and the producing configuration
"Means hide variability" bare means for stochastic output error bars / confidence intervals on every random-output figure
"Theorem numbers don't match the text" label drift single numbering scheme via amsthm; reference by number everywhere
"Scaling claim unsupported" linear-axis time plot log-log size-vs-time plot or a performance profile across the instance set

These are the exhibit-level versions of the two flags that sink OR computational sections: no benchmarks and structure-not-connected-to-application. Because Operations Research is the INFORMS flagship demanding both theorem-grade rigor and a credible computational study, the comparison table and the performance profile carry as much referee weight as the theorem environments.

Worked exhibit pair (illustrative numbers)

A paper proves a 1.5-approximation and validates it. Two exhibits do the persuading:

Comparison table — Method × {assumption, factor, complexity}:

Method Assumption Factor Complexity
Prior (Author year) bounded ratios 2.0 O(n²)
This paper general weights 1.5 O(n² log n)

Computational table — Instance set × {mean gap %, time (s), solver baseline}, e.g. TSPLIB-derived instances showing 1.8% mean gap vs. 31% for the heuristic baseline at a 600 s limit on stated hardware, with the proved 50% bound never violated. The figure pairs them: a log-log scaling plot with confidence-interval bands over 30 seeds. The table corroborates the theorem's bound; the plot shows it holds as size grows.

Execution bridge (StatsPAI / Stata MCP)

Generate exhibits from the fitted result, not by retyping numbers (the usual source of body-vs-appendix drift). Full map: execution-with-mcp. Operations Research is predominantly analytical / optimization / stochastic modeling; use the chain below only for its empirical/causal papers — modeling, optimization, and simulation are outside this causal-inference toolchain.

  • Tables: etable (multi-model columns) or did_summary_to_latex straight from the result_id.
  • Figures: plot_from_result / enhanced_event_study_plot / event_study_table — axis units and the SE/clustering note baked in.
  • Every note names the estimator + clustering and states the effect size in interpretable units.

See a full fitted-result → exhibit chain in the JF execution walkthrough.

Anti-patterns

  • A results table with no time limits, units, or hardware — irreproducible.
  • Bare means for stochastic output with no confidence intervals.
  • A comparison table that omits the closest competitor.
  • Theorem/assumption numbers that drift between text and exhibits.
  • Raster screenshots of plots instead of vector figures.
