Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
open algorithm » mppt algorithm, our algorithm, driven algorithm
based using » based nursing, gases using, based testing
using open » using opencl, using one
parameter » parameters

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( based using open algorithm ) or ( modified parameter optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( based using open algorithm ) OR ( modified parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( based using open algorithm ) or ( modified parameter optimization algorithms ))*.
