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 solution algorithm" » "modified make evolution algorithm", "modified make convolution algorithms", "modified make evolutionary algorithm", "modified male solution algorithm", "modified water solution algorithm", "modified nacl solution 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 make solution algorithm\") OR (\"modified parameters optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified make solution algorithm ) OR ( modified parameters optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make solution algorithm") OR ("modified parameters optimization algorithm"))*.
