Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
response estimation » response optimization, pose estimation, response association
objective solution » objective evolutionary, objective allocation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified response estimation algorithms ) or ( modified objective solution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified response estimation algorithms ) OR ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified response estimation algorithms ) or ( modified objective solution algorithm ))*.
