Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"verified network optimisation algorithm" » "verified network optimization algorithms", "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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective convolution algorithms") OR ("verified network optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) or ( verified network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") or ("verified network optimisation algorithm"))*.
