• If you are trying to use Boolean operators, they must be ALL CAPS: (( policy optimisation algorithm ) OR ( ((game optimisation) OR (game optimization)) algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( policy optimisation algorithm ) or ( ((game optimisation) or (game optimization)) algorithm ))*.
