Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameter optimized algorithms", "modified parameters optimization algorithms"
"modified made estimation algorithms" » "modified made estimation algorithm", "modified made optimisation algorithm", "modified made approximation algorithms", "modified pose estimation algorithms", "modified male estimation algorithms", "modified adam estimation algorithms", "modified df 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 made estimation algorithms") OR ("modified parameter optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified made estimation algorithms ) or ( modified parameter optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made estimation algorithms") or ("modified parameter optimization algorithms"))*.
