Choice map initialization for an sDAG, assuming \(\tau _0\) has higher likelihood than \(\tau _1\). In a are two trees on seven taxa and the sDAG built from the trees. The edges of the sDAG are labeled with the topology, \(\tau _0\) in red or \(\tau _1\) in blue, where the edges first appeared. In b are the two additional topologies in the sDAG. In c we highlight the edges that have an option in the choice maps. In orange is an edge (bold dashed line) and its chosen neighbors (lightweight dashed line), with a choice of parent edge; in purple is an edge and its chosen neighbors, with a choice of right child edge; and in green is an edge and its chosen neighbors, with a choice of parent edge and right child edge
