Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
one algorithm » our algorithm, _ algorithm, mom algorithm
19 using » _ using, ε using
a using » _ using, ε using

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( ((a using) OR (19 using)) one algorithm ) or ( modified parameters optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((a using) OR (19 using)) one algorithm ) OR ( modified parameters optimisation algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((a using) OR (19 using)) one algorithm ) or ( modified parameters optimisation algorithm ))*".
