Perhaps you should try some spelling variations:
"modified near optimization algorithm" » "modified near optimization algorithms", "modified near estimation algorithm", "modified near estimation algorithms", "modified network optimization algorithm", "modified stage optimization algorithm", "modified _ optimization algorithm", "modified seird optimization algorithm", "modified adam optimization algorithm"
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization 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 near optimization algorithm") or ("modified notion optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified near optimization algorithm") OR ("modified notion optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified near optimization algorithm ) or ( modified notion optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified near optimization algorithm") or ("modified notion optimisation algorithm"))*.
