Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithm", "modified notion optimized algorithms", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified pulse estimation algorithms" » "modified pulse estimation algorithm", "modified pulse optimisation algorithm", "modified pulse approximation algorithms", "modified pulses estimation algorithms", "modified pose estimation algorithms", "modified sphere estimation algorithms", "modified male estimation algorithms", "modified passive estimation algorithms"

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 notion optimization algorithms") OR ("modified pulse estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( modified pulse estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("modified pulse estimation algorithms"))*.
