Perhaps you should try some spelling variations:
"modified changing optimisation algorithmsss" » "modified changing optimization algorithms", "modified changing estimation algorithms", "modified changing optimization algorithmssss", "modified changing estimation algorithmsss", "modified changing estimation algorithmssss", "modified staffing optimization algorithmsss", "modified caging 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 objective optimisation algorithm") or ("modified changing optimisation algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithm") OR ("modified changing optimisation algorithmsss")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified changing optimisation algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified changing optimisation algorithmsss"))*.
