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