Perhaps you should try some spelling variations:
"modified choosing optimization algorithms" » "modified choosing optimisation algorithm", "modified choosing estimation algorithm", "modified choosing optimized algorithms", "modified staffing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimization algorithms"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimisation algorithm", "modified notion approximation algorithms", "modified motion estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion estimation algorithms") or ("modified choosing optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithms") OR ("modified choosing optimization algorithms")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithms ) or ( modified choosing optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithms") or ("modified choosing optimization algorithms"))*.
