Upgrade Notes

This repository began as a single exploratory notebook and was later reorganized into a small Python project.

Main Structural Changes

The project was upgraded by introducing:

• solver logic in src/mot_pricing/
• tests for exact, regularized, reporting, and gallery workflows
• packaging metadata and CLI entry points
• gallery generation and machine-readable summaries
• per-experiment markdown reports and structural diagnostics plots
• documentation, CI, release workflows, and publishing workflows

Correctness And Numerical Fixes

Several fixes were especially important:

• unrestricted benchmark interpretation was corrected
• the regularized dual was compared against the appropriate regularized primal quantity
• the overflow-prone regularized update was replaced with a log-space implementation
• convex-order feasibility became an explicit diagnostic rather than an implicit assumption

Effect Of The Upgrade

The package structure makes it easier to:

• rerun experiments reproducibly
• compare exact and regularized results systematically
• inspect diagnostics rather than relying on notebook state
• add new payoffs and gallery examples without restructuring earlier work
• publish the project in a stable form suitable for reuse

The legacy notebook remains part of the project history, but the library now serves as the source of truth.
