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

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