Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
parameter estimation » parameter estimates, parameter optimization
solution algorithms » solution algorithm, convolution algorithms
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( parameter estimation algorithms ) or ( nodal ((solution algorithms) OR (evolution algorithm)) ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( parameter estimation algorithms ) OR ( nodal ((solution algorithms) OR (evolution algorithm)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( parameter estimation algorithms ) or ( nodal ((solution algorithms) OR (evolution algorithm)) ))".
• Adding a wildcard symbol may retrieve word variants: (( parameter estimation algorithms ) or ( nodal ((solution algorithms) OR (evolution algorithm)) ))*.
