Perhaps you should try some spelling variations:
"modified parameter estimation algorithms" » "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimates algorithms"
"modified made optimized algorithms" » "modified made optimized algorithm", "modified made optimizer algorithms", "modified made optimization algorithms", "modified male optimized algorithms", "modified adam optimized algorithms", "modified df optimized algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified made optimized algorithms\") OR (\"modified parameter estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified made optimized algorithms ) OR ( modified parameter estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made optimized algorithms") OR ("modified parameter estimation algorithms"))*.
