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"
"active learning evolution algorithm" » "active learning solution algorithm", "active learning evolutionary algorithm", "active learning convolution algorithms", "active learning convolution algorithm", "active learning emotion algorithm", "machine learning evolution algorithm"

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

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