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

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 bi1 optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( mode control mppt algorithm ) OR ( modified bi1 optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( mode control mppt algorithm ) or ( modified bi1 optimization algorithm ))*.
