Perhaps you should try some spelling variations:
"modified notion optimisation algorithmssss" » "modified notion optimisation algorithm", "modified notion optimization algorithms", "modified network optimization algorithmssss"
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective 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 objective convolution algorithms") or ("modified notion optimisation algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective convolution algorithms") OR ("modified notion optimisation algorithmssss"))*.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( modified notion optimisation algorithmssss ))*.
