Main function.

void simon_trails_graph_transition_matrix_compute ( )

Compute a transition matrix for graph representing the clustering of trails in Simon64 The data for the graph is read from a data file SIMON_CLUSTER_TRAILS_DATFILE written by simon_boost_print_hash_table from a previous call to simon_trail_cluster_search_boost called from test_simon_diff_search_fixed . The data from the file is stored in a vector E of simon_diff_graph_edge_t structures

uint32_t simon_trails_graph_transition_matrix_node_to_index ( std::map< simon_diff_graph_node_t, simon_diff_graph_node_t, simon_diff_graph_node_comp >  V,
const simon_diff_graph_node_t  target 
)

Given a target node (level,dx,dy) and a vector of such nodes return the index of the target node within the vector or return the size of the vector + 1 if the node was not found.

Used in the computation of the transition matrix of the trails graph for Simon.
