Perhaps you should try some spelling variations:
"modified changing optimisation algorithmss" » "modified changing optimization algorithms", "modified changing estimation algorithms", "modified changing estimation algorithm", "modified changing optimization algorithmsss", "modified changing estimation algorithmss", "modified changing estimation algorithmsss", "modified staffing optimization algorithmss", "modified caging optimisation algorithmss"
"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.

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