Companion to the feat(async) commit. Brings every cross-referencing
doc up to v0.8 currency, replaces marketing-flavored copy with plain
prose, and replaces toy benchmark problems with relatable ones that
include actual run output and interpretive narrative.
- README: collapses the four-bullet "Read the user guide / API
reference / Tested with N tests / Hot paths optimized" list into
a single Docs links line.
- README: replaces the Schaffer-N1 toy problem with a PickACar
multi-objective design problem — three decision variables
(displacement, weight, drag), four objectives (price, 0-60,
fuel, noise), and *nonlinear* cost relationships so the Pareto
front is a real surface, not a 1D sweep. Includes actual NSGA-III
run output (representative slice across the 100-car front) and
a narrative explaining what each row tells you and why hand-
picking would miss the interesting tradeoffs.
- README: removes rustdoc-style hidden `#` setup lines from code
blocks. The README is rendered as plain markdown on GitHub /
crates.io, where those lines are visible garbage instead of
hidden setup. Code blocks are now self-contained.
- Guide quickstart (getting-started.md): replaces Sphere ( Σ x² )
with a least-squares LineFit example. Same shape (single-
objective continuous), but recognizable framing. Includes
actual CMA-ES output, residual table, and narrative comparing
the answer to standard regression.
- Algorithm count audit: stale "35 algorithms" claim corrected to
the actual 33 across README, src/lib.rs, introduction.md, and
the comparison.md table cell.
- Async feature flag listed in the optional-features sections of
README, src/lib.rs, getting-started.md.
- introduction.md, choosing-an-algorithm.md, comparison.md,
stability.md, migration.md, cookbook/parallel.md,
cookbook/custom-optimizer.md: cross-references updated to
describe full async coverage and link the new cookbook recipe.
- stability.md: removes the speculative "Observer / Snapshot /
Checkpoint planned" bullet (those didn't ship); documents the
AsyncProblem / AsyncPartialProblem trait stability.
- migration.md: new "To 0.8" section with paths from 0.5.x and 0.7.x.
- CHANGELOG: 0.8.0 entry capturing the async feature plus the
documentation / governance / CI catch-up.
- SECURITY.md: supported versions table reflects 0.8.x.
Async coverage was incomplete in 0.7 (only RandomSearch and
DifferentialEvolution had run_async). 0.8 closes the gap: every one
of the 33 algorithms now exposes
run_async(&problem, concurrency).await, gated on the async feature.
- Population-based algorithms fan out per-generation evaluations
through evaluate_batch_async with concurrency-bounded
FuturesOrdered chunks.
- Steady-state algorithms (HillClimber, SimulatedAnnealing,
OnePlusOneEs, Paes, NelderMead) await each step sequentially;
they accept the concurrency parameter for API uniformity.
- TabuSearch fans out the K-neighbor batch each step.
- Surrogate algorithms (BayesianOpt, Tpe) batch the initial design
and await per-iteration acquisitions sequentially so the surrogate
can update between picks.
- Hyperband uses a new AsyncPartialProblem trait (mirroring
PartialProblem for multi-fidelity workloads) and a parallel
evaluate_batch_at_budget_async helper; each Successive-Halving
rung fans out its budgeted evaluations.
All paths preserve seeded determinism: RNG draws happen on the main
task in the same order as the sync path, and only the evaluations
are concurrent.
Adds a dedicated cookbook recipe at docs/book/src/cookbook/async.md
with a worked example (DifferentialEvolution under tokio) and
guidance on picking concurrency. Cross-references in SUMMARY.md
and cookbook.md are updated to surface the new recipe.
The follow-up docs commit reconciles the rest of the user guide
and README to describe the new feature; this commit is the bare
async surface.
mdbook 0.4.40 (the version pinned in .github/workflows/docs.yml)
doesn't recognize edition = '2024' under [rust], failing the docs
build. Drop to '2021' for the in-book code blocks; the heuropt
crate itself stays on Rust 2024.
Adding [workspace] to the root Cargo.toml made fuzz/Cargo.toml
inherit it, but fuzz isn't in the members list — every fuzz-smoke
job failed with 'current package believes it's in a workspace when
it's not'. Add an empty [workspace] table at the top of
fuzz/Cargo.toml so cargo treats fuzz as the root of its own
workspace and stops walking up.
Theme: documentation and project polish. No public-API changes; this
is the v0.5 release that elevates heuropt's docs/onboarding/governance
to bar-setting status.
Adds:
- mdbook user guide at docs/book/ with intro, getting-started,
defining-problems, choosing-an-algorithm, cookbook (7 recipes),
comparison vs other libraries, stability/SemVer, migration guides.
Deploys to https://swaits.github.io/heuropt/ via .github/workflows/
docs.yml.
- Runnable rustdoc examples on every algorithm (35 of them), all
exercised by cargo test --doc.
- Three real-world examples: portfolio.rs (multi-obj with budget
constraint), hyperparam_tuning.rs (BO + TPE), scheduling.rs
(permutation via SA + SwapMutation against Smith's-rule oracle).
- Governance: CONTRIBUTING.md, SECURITY.md, CODE_OF_CONDUCT.md
(adopting builderscode.org's Builder's Code of Conduct), GitHub
issue templates, PR template.
Polishes:
- README hero with badges + user-guide link.
- lib.rs crate-level docs.
- CHANGELOG entry for 0.5.0.
Bumps Cargo.toml to 0.5.0.
