Transaction Science 980fffc34d wai-quantum: an optimisation stops and goes on to the same bytes ... A long optimisation ran to its end in one process or not at all; one killed partway lost every step. The engine's optimiser now runs from a checkpoint (engine::variational::optimize_resumable, call_optimize): after every step its caller has the run as it stands and may stop it there, and the checkpoint, wai.quantum.optimize-checkpoint/1, holds the steps taken with their links and the optimiser's whole state (the point, Adam's moments and the powers of its betas, SPSA's stream, the best point and the counts), every number as the bits of its f64. Gone on with from any step, a run ends with the same bytes as one that never stopped, for each optimiser; a checkpoint of another request, or one whose steps were changed, is refused (J052). wai-quantum optimize --checkpoint FILE keeps the state in FILE as it goes (at most once a second, and when it stops; written whole or not at all), goes on from FILE when it is there, and removes it when the run ends; a run killed and started again with the same arguments ends with the same bytes, receipt and all. --slice N takes at most N steps, then stops with the state kept (exit 2).
