Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithm, optimized algorithms
location optimization » allocation optimization, static optimization
estimation algorithms » estimation algorithm, optimisation algorithm, approximation algorithms
modified location » modified carbon
robust estimation » robust optimization, pose estimation, risk estimation

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 location optimization algorithms ) OR ( modified robust estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified location optimization algorithms ) or ( modified robust estimation algorithms ))*.
