New exp_map_elites.cpp does not compile

[Aneoshun]

Hi all,
It seems that the new version of the MAP_Elites example, pused 20 days ago, does not compile. I just tried on a ubuntu 18.04, fresh sferes2 clone.

It looks like the include to Eigen is missing, some typedefs are defined several times, the gards are broken.

Does it compile with you?

Does it compile with you?

Which file exactly? Where can we find it?

[Aneoshun]

In the qd branch, in sferes2/examples/ex_map_elites.cpp (this is the default example compiled with a simple ./waf)

[costashatz]

It is not compiling for me...

@jbmouret Could you let me know what was your goal with this commit and if I can go ahead and try to debug it. Thanks.

[jbmouret]

which commit are you referring to? Overall, my last commits were to try to abstract the kind of structure for nearest neighbor s(kd-tree vs partial_sort vs other), but this is clearly a work in progress and it's hard to do it alone (since I am modifying your code and I do not have any easy way to test that I did not break everything).

[Aneoshun]

The last one on the qd branch (83cce55). It does not compile at the moment.

I know that it's hard, I want to help (especially now that I have almost finished teaching for the year).
I will think about a small qd example (like the map_elites example) and see how it can be used to test the different variants of QD.

I suppose I should not have committed this: this is clearly some work in progress (almost done, I think, but still in progress). To my defence, I was in a hospital bed at the time. Maybe I was not 100% focused...

The goal is to replace all the calls to the kdtree to a call to _storage.nearest().

I will try to finish it asap, but if you might want to revert the commit if you need a working version in this branch.

(and yes, I really need your help once it compiles because there are many subtle things in your code that I have to modify and I might break something).

Hoowww, sorry to read this. Francesco briefly told me about it couple of days ago, but I did not know you had to go the hospital, and no need to defend yourself.

I currently ask my students to CO the previous commit, so no need to revert it as it seems to ne almost complete, we just need to patch it.

[Aneoshun]

This is fixed now.
