Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified passive solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution 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 passive solution algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive solution algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified passive solution algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive solution algorithm") or ("modified notion optimization algorithms"))*.
