Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
pre algorithm » mppt algorithm, qspr algorithm, _ algorithm
using pre » nursing pre, using one, using ph
a using » _ using, ε using, 19 using

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( a using pre algorithm ) or ( modified parameters optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( a using pre algorithm ) OR ( modified parameters optimization algorithm ))*.
