Perhaps you should try some spelling variations:
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"verified network estimation algorithm" » "verified network optimization algorithm", "certified network estimation algorithm", "defined network estimation 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: "((\"verified network estimation algorithm\") OR (\"modified parameter optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( verified network estimation algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("verified network estimation algorithm") OR ("modified parameter optimisation algorithm"))*.
