Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
open algorithm » mppt algorithm, our algorithm, driven algorithm
machine using » machines using, machinery using
using open » using opencl, using one

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

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