Perhaps you should try some spelling variations:
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm"
"modified model selection algorithm" » "modified model solution algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified market selection algorithm", "modified male selection algorithm"

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

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