📝 Walkthrough

Walkthrough

Update docs to mark cuOpt MIP as beta and emphasize GPU-accelerated primal heuristics in hybrid GPU/CPU workflows across README, core MILP docs, feature/settings, language bindings, and an FAQ.

Changes

cuOpt MIP Beta and GPU Primal Heuristics Messaging

Layer / File(s)	Summary
Product messaging and core MILP conceptual documentation README.md, docs/cuopt/source/introduction.rst	Expanded README product paragraph; introduction.rst MILP beta note replaced with expanded text including a Mixed Integer Linear Program definition and a rewritten hybrid GPU/CPU workflow that frames GPU primal heuristics as improving the primal bound early and CPU algorithms as improving the dual bound.
Feature availability and MIP settings documentation docs/cuopt/source/milp-features.rst, docs/cuopt/source/mip-settings.rst	Updated Availability text to mark MIP as beta and describe GPU-accelerated primal heuristics focus; fixed grammar ("provide" → "provides"); added MIP-specific introductory paragraph in mip-settings describing beta status and heuristic emphasis.
API language-specific documentation docs/cuopt/source/cuopt-c/mip/index.rst, docs/cuopt/source/cuopt-cli/index.rst, docs/cuopt/source/cuopt-python/mip/index.rst	Inserted consistent beta-status notes and GPU-accelerated primal-heuristics descriptions across C, CLI, and Python docs.
User FAQ for MIP solver usage docs/cuopt/source/faq.rst	Added FAQ "How do I run the MIP solver with cuOpt?" describing usage via Python/C/CLI/server APIs, MIP beta status, GPU-accelerated primal heuristics for early feasible-solution finding, and that proving optimality is still under active development.

425-433: ⚡ Quick win

Remove redundant sentence for consistency with canonical source.

Lines 431-432 add an extra sentence ("These GPU algorithms are designed to improve the quality of feasible solutions early in the solve.") not present in the canonical wording from introduction.rst. This sentence restates what was already conveyed about GPU-accelerated primal heuristics finding high-quality feasible solutions quickly.

Based on learnings, the .rst files under docs/cuopt/source/ are the canonical source for published docs; introduction.rst establishes the standard beta/GPU-heuristics messaging that other pages should mirror.
