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 adam optimization algorithmsss" » "modified adam optimization algorithms", "modified adam estimation algorithms", "modified game optimization algorithmsss", "modified stage optimization algorithmsss", "modified _ optimization algorithmsss", "modified df optimization algorithmsss", "modified near optimization 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 adam optimization algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("modified adam optimization algorithmsss")).
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified adam optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified adam optimization algorithmsss"))*.
