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