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