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