there are many MPPT algorithms however AI algorithms has proven superior performance over traditional algorithms. in literature you will find that hopfield NN reaches very high accuracy however it needs learning data 

you can refer to my following article 

Intelligent Techniques for MPPT Control in Photovoltaic Systems: A Comprehensive Review

 Yes dear Hugh  ! thank you all 

the choice depends on the expected solar source (clouds, dirt, etc) and on sensors and computational power requirements (i.e. cost). As with everything in engineering, the best performing solution is not the optimal solution for the system. 

Thank you dear Andrea
