Perhaps you should try some spelling variations:
"modified adam approximation algorithm" » "modified adam approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"
"modified topology optimisation algorithm" » "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology estimation algorithms", "modified topology optimization algorithm", "modified policy optimization algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified topology optimisation algorithm") OR ("modified adam approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified topology optimisation algorithm ) or ( modified adam approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified topology optimisation algorithm") or ("modified adam approximation algorithm"))*.
