Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
thanh algorithm » graph algorithms, search algorithm
van thanh » ban thanh, van tuan
code van » corne van, de van, cong van

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( code van thanh algorithm ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( code van thanh algorithm ) or ( modified parameter optimisation algorithm ))*.
