Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
source algorithm » our algorithm, search algorithm
using source » using force, using morse
based using » based nursing, gases using, based testing

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 source algorithm ) or ( modified parameters optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( based using source algorithm ) OR ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( based using source algorithm ) or ( modified parameters optimization algorithms ))*.
