Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
source algorithm » our algorithm, search algorithm
1 source » a source, _ sources
core 1 » core _

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( core 1 source algorithm ) or ( modified parameters optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( core 1 source algorithm ) OR ( modified parameters optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( core 1 source algorithm ) or ( modified parameters optimisation algorithm ))*.
