Perhaps you should try some spelling variations:
"modified near optimisation algorithm" » "modified near optimization algorithms", "modified near estimation algorithm", "modified near estimation algorithms", "modified _ optimisation algorithm", "modified network optimization algorithm", "modified seird optimisation algorithm", "modified adam optimisation algorithm"
"modified positive evolution algorithm" » "modified positive solution algorithm", "modified positive evolutionary algorithm", "modified positive convolution algorithms", "modified positive solutions algorithm", "modified passive evolution algorithm", "modified adaptive evolution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified positive evolution algorithm") or ("modified near optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified positive evolution algorithm") OR ("modified near optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( modified positive evolution algorithm ) or ( modified near optimisation algorithm ))*.
