How does the sampler (tpe) handle the different trial states?

See original GitHub issue

Hi, a trial can have different states:

    RUNNING = 0
    COMPLETE = 1
    PRUNED = 2
    FAIL = 3
    WAITING = 4

When the sampler (tpe) sees these trials in a database when a new trial starts - how does it handle them? It uses completed trials to get a signal on the fitness landscape to select the next parameter set. But how does it handle FAILed, PRUNED and RUNNING trials? Does it just ignore them?

This question is connected to this item: #913

Thanks Philip

@sile Thanks for this explanation. Now I understood.

Should we (I as a PR) put this explanation to the documentation here: https://optuna.readthedocs.io/en/latest/reference/samplers.html#optuna.samplers.TPESampler

What do you think?
