Plan a reaction optimisation in rounds. List the variables and their values. Round 1 is the conditions to start with, spread over all the combinations. Type the results back and the tab proposes round 2, then round 3, and so on. It keeps every round and the best so far, and plots every run by round. It never proposes a condition you did not list.
A suggestion is not a guarantee of an optimum. No gain for a while is not proof that the search is finished. Noise in a measurement looks like chemistry unless a run is repeated.
One column per round, one dot per run; the height is the result. Hover a dot to see its conditions. Label puts a variable's value beside every dot.
Off at the start. With it on, a fifth of each round, from round 2, is drawn at random from untried conditions. Over many repeats those runs alone reach the top 5 % in at least the stated share: a floor, not this search's chance.
No. The only request is an anonymous visit count to this site, with nothing you typed. Nothing is kept in the browser, not even the theme. A file is read only when you open one, and written only when you press Save or Export CSV.
Yes. Type a password beside Save, and again to match: the file is encrypted, and nobody can open or recover it without the password. With no password the file is plain, readable text. Export CSV is never locked.
From the results so far, the tab learns which values of each variable work well, then picks untried conditions that look good or are still unknown. More results, better picks.
Up to 5,000 conditions: every combination of the values you list. Numbers are numbers (80 is nearer 100 than 120); words are separate choices.
