Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"order control mppt algorithm" » "order control mom algorithm", "order control qspr algorithm", "mode control mppt algorithm", "error control mppt algorithm", "order control mpc algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("order control mppt algorithm") OR ("modified multiobjective optimization algorithm"))~.
• Removing quotes may allow a broader search: (( order control mppt algorithm ) or ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("order control mppt algorithm") or ("modified multiobjective optimization algorithm"))*.
