Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"modified model solutions algorithm" » "modified model solution algorithm", "modified model evolution algorithm", "modified model evolutionary algorithm", "modified nodal solution algorithm", "modified global solutions algorithm", "modified male solutions algorithm"

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 model solutions algorithm\") OR (\"modified parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified model solutions algorithm ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified model solutions algorithm") OR ("modified parameters optimization algorithms"))*.
