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