Perhaps you should try some spelling variations:
"modified make optimisation algorithmss" » "modified make optimization algorithms", "modified make estimation algorithms", "modified make estimation algorithm", "modified make optimization algorithmsss", "modified make estimation algorithmss", "modified make estimation algorithmsss", "modified market optimization algorithmss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified male 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 make optimisation algorithmss") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified make optimisation algorithmss ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make optimisation algorithmss") or ("modified objective optimisation algorithm"))*.
