lobo 4432e38cd2 feat(ant-colony): add ant colony optimization demo for tsp 
Ant System on the travelling salesman problem, run on the CPU.
Click the canvas to add cities while the colony runs.
Show the nearest-neighbor tour as a baseline. Tick ROADMAP.

Roadmap

Open ideas for the playground frontend. Tick a box when done.

Quick wins

  • Labyrinth grid size crash: labyrinth.component.html still binds [gridRows]; typed sizes above the max crash the page. Same fix as pathfinding (clamp in code, drop the binding).
  • Fourier circles slider thumb: at "Circles: 256" the thumb sits near the left end, like at 30. Check max/value binding of the circles mat-slider (seen 2026-10-14, not verified).
  • Lighthouse gate: add an assert block to lighthouserc.json (e.g. performance, accessibility, SEO >= 0.9). Today CI runs the audit but never fails. Note: the @lhci/cli → lighthouse 13 override in package.json is only safe without assert. Check it again before you add one.
  • robots.txt + sitemap.xml: static files in public/, listing all routes from app.routes.ts.
  • SEO per algorithm page: all algorithm routes use data: { seo: 'ALGORITHMS' }. Give each one its own key and add SEO.<KEY>.TITLE / DESCRIPTION to en.json and de.json.
  • nginx security headers: no CSP, X-Content-Type-Options, Referrer-Policy, frame-ancestors in nginx.conf (gzip done). First check with curl -I https://andreas-dahm.eu/ if the reverse proxy already sets them.

Tests

  • seo.service.ts: spec for title/meta update on route change and language change.
  • Pure logic without specs: pathfinding-animator.ts, cloth and pendulum GPU strategies (the math around them, not the shaders), fractal3d.

Features

  • Shareable demo state: keep demo settings in query params (fractal zoom/center, sorting algorithm, seeds). Opening the link restores the view.
  • New algorithm demos (pattern: route + RouterConstants + AlgorithmsService entry + i18n + information panel):
    • Boids / flocking (GPU path like cloth)
    • Physarum (slime mold transport networks, trail map on GPU compute, CPU fallback)
    • Boids 3D (later, 2D done)
    • Voronoi / Delaunay
    • A* vs Dijkstra side by side (reuse pathfinding)
    • Fourier epicycles
    • Reaction-diffusion (Gray-Scott) shader (reuse the fractal shader setup)
    • Ant colony (ACO on TSP, CPU + Canvas 2D)
