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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("code control qspr algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code control qspr algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( code control qspr algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code control qspr algorithm") or ("modified multiobjective optimisation algorithm"))*.
