gmravi2003 bffbbdfcb3 Buggy. Couldnt debug it 2008-02-09 21:58:58 +00:00
Dongryeol Lee 47fd5fa9ad Renamed the naive algorithm to handle locally constant regression 2008-02-09 21:23:50 +00:00
vasiloglou 85aa1036b9 I had forgotten to add the test 2008-02-09 19:18:39 +00:00
vasiloglou 151a985de7 seems to run although it needs to be cross tested with a swiss roll example to 
verify it. We are a little bit worried that the nearest neighbors might be wrong
and we have to check on that, because the optimum solution is 9% off the deasible
set. Need also to inser the constraint that the data are centered around zero.
