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"
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization 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 parameter optimisation algorithm\") OR (\"modified network optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) OR ( modified network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithm") OR ("modified network optimization algorithm"))*.
