Perhaps you should try some spelling variations:
"modified a optimized algorithm" » "modified a optimized algorithms", "modified a optimizer algorithms", "modified _ optimized algorithm", "modified _ optimize algorithm", "modified df optimized algorithm", "modified adam optimized algorithm"
"modified adamdamdamdamdamdaptive estimation algorithm" » "modified _damdamdamdamdamdaptive estimation algorithm", "modified dfdamdamdamdamdamdaptive estimation algorithm", "modified adamdamdamdamdamdamdaptive estimation 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: (("modified adamdamdamdamdamdaptive estimation algorithm") or ("modified a optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adamdamdamdamdamdaptive estimation algorithm") OR ("modified a optimized algorithm")).
• Removing quotes may allow a broader search: (( modified adamdamdamdamdamdaptive estimation algorithm ) or ( modified a optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adamdamdamdamdamdaptive estimation algorithm") or ("modified a optimized algorithm"))*.
