Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
search algorithm » source algorithm
based search » based research, based sers
code based » model based, coal based, income based

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

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