Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"code using mental algorithm" » "code using genetic algorithm", "code using control algorithm", "code using mppt algorithm", "code using metal algorithm", "code nursing mental algorithm", "code using medical algorithm", "core using mental 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 using mental algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code using mental algorithm") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( code using mental algorithm ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code using mental algorithm") or ("modified objective optimisation algorithm"))*.
