Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
convolution algorithm » convolution algorithms, evolution algorithm, solution algorithm
spreading convolution » learning convolution
during spreading » during freezing, during weaning
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: (( during spreading convolution algorithm ) or ( modified parameter optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( during spreading convolution algorithm ) OR ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( during spreading convolution algorithm ) or ( modified parameter optimization algorithm ))*.
