Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
network estimation » network optimization
mppt algorithm » mom algorithm, qspr algorithm
mode control » case control, mimo control
control mppt » control mpc

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