Perhaps you should try some spelling variations:
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified passive » modified adaptive
passive solution » positive solutions, saline solution
control adam » control a
control law » control a, contract law, control case

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( mode ((control adam) OR (control law)) algorithm ) or ( modified passive solution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( mode ((control adam) OR (control law)) algorithm ) OR ( modified passive solution algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( mode ((control adam) OR (control law)) algorithm ) or ( modified passive solution algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( mode ((control adam) OR (control law)) algorithm ) or ( modified passive solution algorithm ))*.
