Perhaps you should try some spelling variations:
"modified network optimization algorithm" » "modified network optimization algorithms", "modified network optimisation algorithm", "modified network estimation algorithm", "certified network optimization algorithm", "defined network optimization algorithm", "modified near optimization algorithm"
"modified time convolution algorithms" » "modified time evolution algorithm", "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male convolution algorithms"

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 network optimization algorithm\") OR (\"modified time convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) OR ( modified time convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") OR ("modified time convolution algorithms"))*.
