New entries start at 1, so decaying to anything less than 1 OnQuit will give the new entries a better chance at affecting results (and surviving when we remove infrequently used input histories).

"Rebalance" all results by shrinking them by 99%. This will be called OnQuit which will trigger the paranoid expiration.

Comment on attachment 291076 [details] [diff] [review] v1 Decaying once-used selections (use_count of 1) would be helpful for new entries to show up that enter with a value of 1 when showing adaptive results. Additionally, this will help slowly decay previously-used adapted results to allow for new adapted results.

Comment on attachment 291076 [details] [diff] [review] v1 looks good, r=me

I'll probably bump up the decay to .9 instead of .99. That will take ~20 times for a once-used adapted result to drop to .1 whereas .99 would still be around .36 after 100 times. This is more interesting for the more commonly used adaptive results for allowing new adapted results showing up faster. Positive reinforcement of selecting the results will keep the adapted results up.

I think this made autocompleting worse for me over the last few days. While the first result used to be the one that I looked for very often, it's now the second or third result more frequently. Maybe .9 instead of .99 was a little drastic.

Any examples in particular? The decay is applied to all inputs, so anything that was ranked higher will stay ranked higher.

Right, it's applied to all use counts, so I can't really explain what I was seeing. Maybe there was another change that I don't know of?
