...or even as a fully stand-alone submission.

The concept is really pretty good, why not publish?

Overall organisation will just be clearer that way

Like, what happened to the non-dominated-sort C-file?
→ Profile, profile, profile.

and implement/integrate them into the optimizer.

None except the DEMO exist.

Hi Rodyo, I have a multi-objective optimization with 3 objective functions and 2 decision variables. Now, I'm trying to plot the Pareto Front launching two algorithms at the same time {'ASA', 'GA'}. Unfortunately Godlike fails to work and returns to output an error message:

........................................................................
??? Subscripted assignment dimension mismatch.

Error in ==> GODLIKE>interchange_populations at 629
crowding_distances(lfe2+1:lfe2+2*popsz, :) = popinfo.crowding_distance;

Error in ==> GODLIKE at 171
pop = interchange_populations(pop);

Error in ==> buck_of_sa_ga at 55
[s0,fval_sa,pareto_indiv,pareto_obj,exitflag,output] = GODLIKE({of1,of2,of3},PS,lb,ub,{'ASA','GA'},options_sa);
..........................................................................

I want to clarify that with 2 objective functions, everything works well, in fact if I write GODLIKE({of1, of2},...) , Godlike works. Why if I add the third objective function it does not work anymore? It is not possible to obtain the comparison between the various algorithms with an objective function of three values?

Can you help me?

Thanks

The documentation shall be much more detailed, and brought to scientific-journal quality.

the need to define [lb ub] confines GODLIKE to bound-constrained problems

GODLIKE settings, parameters and variables at the top of the function body, create clutter. A configuration object (or simple struct) could provide a way to de-clutter this, as well as make it easier to share that information with the helper functions.

An alternative would be to transform GODLIKE into a class, and create a new top-level function called "GODLIKE" that does nothing but call & use that class.

There's no Contents.m either.

Defaults:

• fmincon, if toolbox available
• minimize, if available
• fminsearch, if nothing is available and problem is unconstrained
• none, if all that fails.

...and integrate any new, important insights
