Perhaps you should try some spelling variations:
"modified based optimisation algorithms" » "modified based optimization algorithms", "modified based estimation algorithms", "modified based estimation algorithm", "modified based optimization algorithmss", "modified based estimation algorithmss", "modified game optimization algorithms", "modified male optimisation algorithms"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

You may be able to get more results by adjusting your search query.

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