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 make estimation algorithms" » "modified make estimation algorithm", "modified make optimization algorithms", "modified make optimisation algorithm", "modified pose estimation algorithms", "modified male estimation 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 make estimation algorithms\") OR (\"modified parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified make estimation algorithms ) OR ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make estimation algorithms") OR ("modified parameters optimization algorithm"))*.
