Perhaps you should try some spelling variations:
"modified time convolution algorithms" » "modified time evolution algorithm", "modified time solution algorithm", "modified time evolution algorithms", "modified bi1 convolution algorithms", "modified male convolution algorithms"
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation 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 time convolution algorithms") or ("modified network optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time convolution algorithms") OR ("modified network optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified time convolution algorithms ) or ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified time convolution algorithms") or ("modified network optimisation algorithm"))*.
