Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"mapping learning convolution algorithm" » "mapping learning convolution algorithms", "mapping learning evolution algorithm", "mapping learning solution algorithm", "machine learning convolution algorithm", "enabling learning convolution 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: (("mapping learning convolution algorithm") or ("modified network optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning convolution algorithm") OR ("modified network optimization algorithm")).
• Removing quotes may allow a broader search: (( mapping learning convolution algorithm ) or ( modified network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning convolution algorithm") or ("modified network optimization algorithm"))*.
