Perhaps you should try some spelling variations:
"modified robust optimisation algorithm" » "modified robust optimization algorithms", "modified robust estimation algorithm", "modified robust estimation algorithms", "modified robust optimization algorithm"
"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.

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