Perhaps you should try some spelling variations:
estimation deterministic » estimators deterministic, optimization deterministic, optimisation deterministic
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming
array using » arrays using
systems r » systems real

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: estimation deterministic systems r ((((array string) OR (array using))) OR (array sharing))~.
• Adding a wildcard symbol may retrieve word variants: estimation deterministic systems r ((((array string) or (array using))) or (array sharing))*.
