Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
2 algorithm » _ algorithm, _ algorithms, _ algorithmic
speaking 2 » speaking _, speaking 4, speaking icu
core » more, care

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: (( (code OR core) speaking 2 algorithm ) OR ( modified parameters optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (code OR core) speaking 2 algorithm ) or ( modified parameters optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( (code OR core) speaking 2 algorithm ) or ( modified parameters optimisation algorithm ))*.
