Examples
Worked optimization cases, from first run to real layouts
A growing set of worked examples, from analytic benchmarks to realistic accelerator cases. Each one ships as a ready‑to‑run ZIP archive with the GIOTTO input (GIN) and its supporting files: download it, inspect it, and use it as a starting point for your own studies. Each card gives a short note on the goal of the optimization.
Focusing channel
A compact beam‑optics case: tuning the focusing elements of a transport channel to keep the beam envelope under control along the line. A good first run to see how GIOTTO drives the beam‑dynamics ASTRA code and how a GIN is organized.
Travelling Salesman Problem
The classic Travelling Salesman Problem: find the shortest closed tour through a set of cities. A pure combinatorial benchmark, with no beam dynamics involved, useful to watch the genetic engine at work on a problem with a well‑known structure.
Rastrigin function
Minimization of the Rastrigin function, a standard multimodal benchmark with a regular grid of local minima around the global one. It shows how the genetic search escapes local traps and converges to the global optimum.
Dog‑leg and dispersion
A dog‑leg transfer line with dipoles and quadrupoles, optimized to close the dispersion (η, η′) at the exit while preserving beam quality. Representative of a realistic accelerator layout study.
