Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
seird approximation » time approximation, network approximation
market optimization » game optimization, parameter optimization, market capitalization
modified market » modified male
modified seird » modified near

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 seird approximation algorithms ) OR ( modified market optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified seird approximation algorithms ) or ( modified market optimization algorithms ))*.
