Perhaps you should try some spelling variations:
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 approximation algorithms"

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 invasive evolution algorithm") OR ("modified df approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified df approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithm") or ("modified df approximation algorithms"))*.
