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