Perhaps you should try some spelling variations:
"modified aging optimization algorithms" » "modified aging optimisation algorithm", "modified aging estimation algorithms", "modified aging estimation algorithm", "modified staffing optimization algorithms", "modified game optimization algorithms", "modified caging optimization algorithms"
"modified notion optimized algorithms" » "modified notion optimized algorithm", "modified notion 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 notion optimized algorithms") or ("modified aging optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimized algorithms") OR ("modified aging optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified notion optimized algorithms ) or ( modified aging optimization algorithms ))*.
