Perhaps you should try some spelling variations:
parameters optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
sach algorithm » search algorithm, graph algorithms, source algorithm
1 sach » 5 sach, a sach
code » core

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 1 sach algorithm ) OR ( modified parameters optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( code 1 sach algorithm ) OR ( modified parameters optimisation algorithm ))*.
