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"
"code using method algorithm" » "code using mom algorithm", "code nursing methods algorithm", "code focusing method algorithm", "code using metal algorithm", "core using method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("code using method algorithm") or ("modified game optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code using method algorithm") OR ("modified game optimization algorithm")).
• Removing quotes may allow a broader search: (( code using method algorithm ) or ( modified game optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code using method algorithm") or ("modified game optimization algorithm"))*.
