Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
research algorithm » search algorithm
code clinical » novel clinical, post clinical, pre clinical

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

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