Perhaps you should try some spelling variations:
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters approximation algorithms"
"modified game estimation algorithm" » "modified pose estimation algorithm", "modified game optimization algorithm", "modified male estimation algorithm", "modified adam 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 game estimation algorithm") or ("modified parameters estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified game estimation algorithm") OR ("modified parameters estimation algorithms")).
• Removing quotes may allow a broader search: (( modified game estimation algorithm ) or ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified game estimation algorithm") or ("modified parameters estimation algorithms"))*.
