Perhaps you should try some spelling variations:
"modified parameter optimisation algorithm" » "modified parameter optimization algorithms", "modified parameter estimation algorithm", "modified parameter estimation algorithms", "modified parameter optimization algorithm"
"modified passive solutions algorithms" » "modified passive solution algorithm", "modified passive evolution algorithm", "modified passive convolution algorithms", "modified positive solutions algorithms", "modified adaptive solutions algorithms"

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

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