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 allocation estimation algorithmss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithms", "modified allocation optimization algorithmss", "modified motion estimation algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters optimization algorithm") OR ("modified allocation estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithm\") OR (\"modified allocation estimation algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) OR ( modified allocation estimation algorithmss ))*.
