Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
controlled source » controlled study
order controlled » order control, target controlled, time controlled
source algorithm » our algorithm, search algorithm

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( order controlled source algorithm ) OR ( modified parameter optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( order controlled source algorithm ) OR ( modified parameter optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( order controlled source algorithm ) OR ( modified parameter optimisation algorithm ))*.
