Fix #201: focussearch now handles discrete vector parameters (cont.) #257

jakob-r · 2016-09-19T14:02:09Z

I was not able to take over PR #202 and keep it there. But I was able to pull the branch here it is

also general focussearch bugfixes

Parameters that have discrete vector params in their requirement can not be handled by infillOptFocus, so trying to do that now gives an error.

we need the updated discrete.vector.mapping outside of the lapply

This is not what assert is for. Use expect_is/expect_true and expect_subset

i will take this now.

ja-thomas · 2016-11-24T15:32:10Z

Just had a look,

a) general look/review
b) rebased to master
c) fixed most of the stuff michel mentioned

afaik good2go now (if travis is green)

ja-thomas · 2016-12-19T08:59:48Z

ping @berndbischl

berndbischl · 2016-12-23T16:47:56Z

this is really not so good what happens here:

i cannot reproduce the error with the suggested new unit test. if i run that test, without further code changes, no error is reproduced. so the unit test is not "catching"
the suggested fix looks suboptimal. code becomes cluttered and unelegant. my suggestion is:
use the new splitVectorParamsFunction from PH, convert the parset in the focus-search to only "single" params and work on those. that should be much simpler.

jakob-r · 2017-01-05T11:01:08Z

Okay. So we are waiting for the PR in ParamHelpers for "splitVectorParamsFunction" and then we will refactor the code.
