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