Perhaps you should try some spelling variations:
"modified adaptive optimisation algorithmsss" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithms", "modified adaptive optimization algorithmssss", "modified adaptive estimation algorithmsss", "modified adaptive estimation algorithmssss", "modified passive optimisation algorithmsss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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