Perhaps you should try some spelling variations:
"modified parameter estimates algorithms" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimizer algorithms"
"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"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameter estimates algorithms") OR ("modified caging optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter estimates algorithms\") OR (\"modified caging optimized algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameter estimates algorithms ) OR ( modified caging optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter estimates algorithms") OR ("modified caging optimized algorithms"))*.
