Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters optimized algorithms"
"modified game estimation algorithms" » "modified game estimation algorithm", "modified game optimisation algorithm", "modified game approximation algorithms", "modified pose estimation algorithms", "modified game optimization algorithms", "modified male estimation algorithms", "modified adam estimation algorithms"

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 parameters optimization algorithms") or ("modified game estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified game estimation algorithms")).
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified game estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified game estimation algorithms"))*.
