Perhaps you should try some spelling variations:
convolution algorithms » evolution algorithm
solution algorithm » evolution algorithm, evolutionary algorithm, estimation algorithm
modified learning » mobile learning, modified caging
modified passive » modified adaptive
passive solution » positive solutions, saline solution

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive solution algorithm ) OR ( modified learning convolution algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified passive solution algorithm ) OR ( modified learning convolution algorithms ))*.
