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"
"model learning evolution algorithm" » "model learning solution algorithm", "model learning evolutionary algorithm", "model learning convolution algorithms", "model learning convolution algorithm", "model learning emotion algorithm", "mobile learning evolution algorithm"

Try widening your search to All Fields.

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

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