Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
location optimisation » allocation optimization
estimation algorithms » estimation algorithm, optimization algorithms, 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 optimisation algorithm ) OR ( modified robust estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified location optimisation algorithm ) or ( modified robust estimation algorithms ))*.
