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