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