Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"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"

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