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 invasive solution algorithm" » "modified invasive evolution algorithm", "modified invasive convolution algorithms", "modified invasive evolutionary algorithm", "modified passive 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 notion optimization algorithms") or ("modified invasive solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithms") OR ("modified invasive solution algorithm"))*.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( modified invasive solution algorithm ))*.
