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

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 solution algorithm ) or ( modified network estimation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified time solution algorithm ) OR ( modified network estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified time solution algorithm ) or ( modified network estimation algorithm ))*.
