Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"code control mpc algorithm" » "code control mppt algorithm", "code control mom algorithm", "code control qspr algorithm", "mode control mpc algorithm", "case control mpc 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: (("code control mpc algorithm") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( code control mpc algorithm ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("code control mpc algorithm") or ("modified multiobjective optimization algorithms"))*.
