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"
"modified make optimisation algorithmsss" » "modified make optimization algorithms", "modified make estimation algorithms", "modified make optimization algorithmssss", "modified make estimation algorithmsss", "modified make estimation algorithmssss", "modified market optimization algorithmsss", "modified game optimization algorithmsss", "modified stage optimization algorithmsss", "modified male optimisation algorithmsss"

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