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 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"

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