Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"
"modified caging optimized algorithmss" » "modified caging optimized algorithms", "modified caging optimized algorithm", "modified caging optimizer algorithms", "modified aging optimized algorithmss", "modified changing optimized algorithmss", "modified charging optimized algorithmss"

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