Computational Resources
Brachistochrone Cycloid and Travel Time
Julia 1.10.12 · Precomputed results
Cycloid endpoint parameters solved by bisection with the complete iteration history saved; independent piecewise-linear travel-time estimates show convergence to the exact cycloid time. Includes three endpoint regimes, saved data, source and an offline interactive explorer.
