Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
our algorithm » source algorithm, qspr algorithm, _ algorithm
learning our » learning due, learning _, learning a
a learning » _ learning, _ learing, how learning

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

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