[NEMO-devel] Result difference

[Ben Elliston]

Hi Yusak

First, rather than sending huge amounts of output to the list, can you
consider using a web service like pastebin.com and sending a link
instead? Thanks.

If I understand correctly, you are asking why the result for iteration
#99 is higher than the final result.  This is because the CMA-ES
algorithm does not guarantee that each generation will always be
better than the previous.  It often explores more widely and can
produce a poorer solution than the overall best.  That is what the
"hallfame" (Hall of Fame) column shows you -- the all-time best. In
this case, that is $51.3702/MWh.

Cheers, Ben
