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