Patent ID: 8200693

Claim:
An article comprising a non-transitory machine-readable storage medium embodying instructions that when performed by one or more machines result in operations comprising: receiving a request to compare a first strategy to a second strategy, the first strategy graphically represented by a first set of linked nodes, the second strategy graphically represented by a second set of linked nodes, each set of linked nodes linking a root node to at least one action node; identifying a subset of linked nodes from at least one of the first set of linked nodes and the second set of linked nodes based on an equivalence of a first subset of the first set of linked nodes to a second subset of the second set of linked nodes; and determining the equivalence of the first subset to the second subset by subtracting a third subset of linked nodes from the first set of linked nodes and from the second set of linked nodes, the third subset representing one or more logical conditions corresponding to a common action from the first strategy and the second strategy; providing a visual depiction of the identified subset of the linked nodes to a user, the visual depiction corresponding to the equivalence of the first subset to the second subset.
