Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
mppt algorithm » mom algorithm, qspr algorithm
modified adam » modified near
mode control » case control, mimo control
control mppt » control mpc
modified df » modified _, modified bi1

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( mode control mppt algorithm ) or ( ((modified df) OR (modified adam)) optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( mode control mppt algorithm ) OR ( ((modified df) OR (modified adam)) optimization algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mode control mppt algorithm ) or ( ((modified df) OR (modified adam)) optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( mode control mppt algorithm ) or ( ((modified df) OR (modified adam)) optimization algorithm ))*.
