Perhaps you should try some spelling variations:
"modified make optimisation algorithmssssss" » "modified make optimisation algorithm", "modified make optimization algorithms", "modified market optimization algorithmssssss", "modified game optimization algorithmssssss", "modified stage optimization algorithmssssss", "modified male optimisation algorithmssssss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"

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 objective optimization algorithm") OR ("modified make optimisation algorithmssssss"))~.
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( modified make optimisation algorithmssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") or ("modified make optimisation algorithmssssss"))*.
