// As we are visualizing the graph, we will make some tweaks to the generated dot file to make
// routing more tractable for Graphviz as well as (hopefully) more legible for the user.
//
// NOTE: It's possible, even likely, that better algorithms are available here. I just tried a
// few different things without doing much research, and this seemed to work well. Please feel
// free to improve on this. --amprocte
//
// -----------------
//
// The first tweak is to trim edges that, intuitively speaking, have long "skip distance". For
// example:
//
// [Actual Graph Structure]      [Visualization]
//    n0                             n0
//    | \                            |  \
//    n1 \                           n1  [to n50]
//    |   |                          |
//    n2  |                          n2
//    |   |                          |
//    n3  |                          n3
//    |   |                          |
//   ...  |                         ...  [from n0]
//    |  /                           |  /
//   n50                            n50
//
// This is useful for training graphs especially, which tend to have very long feed-forward edges
// for intermediate values from fprop being stored for later reuse in the bprop phase.
//
// Efficiently detecting a "long skip" is a bit tricky. We want to come up with a metric that is
// reasonably fast to compute, but does not result in cuts that will split the graph into multiple
// components. The heuristic we are using for the jump distance between n and m is the maximum
// difference in maximum path length from n and m to any result node that is reachable from both
// n and m (or 0, if no such result node exists). Not sure if this is mathematically *guaranteed*
// not to split graph components, but it seems to work well in practice.
//
// Formally:
//
// Compute-Heights-Above-Each-Parameter(N):
//    Inputs: nodes N; define R={n in N | n is a Result node}
//    Output: height_maps: map from N to (map from R to int)
//
//    height_maps is initially empty
//
//    for each r in R:
//        Insert into height_map the map {r -> 1}
//
//    for each n in N in reverse topological ("results-first") order:
//        for each user m of n:
//            for each r in height_maps[m].keys:
//                height_maps[n][r] := max(height_maps[n][r], height_maps[m][r]+1)
//
// Jump-Distance(n,m,height_maps):
//     Inputs: n (source node), m (destination node), height_maps (pre-computed above)
//     Output: jump_distance: int
//
//     jump_distance := 0
//
//     for each r in height_maps[n].keys:
//         if r is in height_maps[m].keys:
//             jump_distance := max(jump_distance, abs(height_maps[n][r] - height_maps[m][r]))
//
// Later on, if E is an edge from n to m, and Jump-Distance(n,m,height_map) > K (where K is kind
// of arbitrary but currently set to 20), we will "cut" the edge as illustrated above.
//
// -----------------
//
// The second tweak aims to eliminate routing pressure from nodes that have large outdegree and
// are connected to many otherwise-distant places in the graph. For this, the only thing we are
// doing at the moment is to "float" Parameter and Constant nodes. This means that rather than
// visualizing them as a single node (which might have very large outdegree as in, e.g., a
// learning rate parameter being fed to many different places), we make a "copy" of the node at
// each occurrence site (with a dashed outline).
//
// NOTE: This tweak could probably be extended to float other kinds of nodes with high out-degree.
// (This situation is likely to arise after constant subexpression elimination.) Here one has to
// be careful to avoid splitting the components. I have some rough ideas on how this could be
// dealt with, but have not had time to implement them yet. --amprocte

// As we are visualizing the graph, we will make some tweaks to the generated dot file to make
// routing more tractable for Graphviz as well as (hopefully) more legible for the user.
//
// NOTE: It's possible, even likely, that better algorithms are available here. I just tried a
// few different things without doing much research, and this seemed to work well. Please feel
// free to improve on this. --amprocte
//
// -----------------
//
// The first tweak is to trim edges that, intuitively speaking, have long "skip distance". For
// example:
//
// [Actual Graph Structure]      [Visualization]
//    n0                             n0
//    | \                            |  \
//    n1 \                           n1  [to n50]
//    |   |                          |
//    n2  |                          n2
//    |   |                          |
//    n3  |                          n3
//    |   |                          |
//   ...  |                         ...  [from n0]
//    |  /                           |  /
//   n50                            n50
//
// This is useful for training graphs especially, which tend to have very long feed-forward edges
// for intermediate values from fprop being stored for later reuse in the bprop phase.
//
// Efficiently detecting a "long skip" is a bit tricky. We want to come up with a metric that is
// reasonably fast to compute, but does not result in cuts that will split the graph into multiple
// components. The heuristic we are using for the jump distance between n and m is the maximum
// difference in maximum path length from n and m to any result node that is reachable from both
// n and m (or 0, if no such result node exists). Not sure if this is mathematically *guaranteed*
// not to split graph components, but it seems to work well in practice.
//
// Formally:
//
// Compute-Heights-Above-Each-Parameter(N):
//    Inputs: nodes N; define R={n in N | n is a Result node}
//    Output: height_maps: map from N to (map from R to int)
//
//    height_maps is initially empty
//
//    for each r in R:
//        Insert into height_map the map {r -> 1}
//
//    for each n in N in reverse topological ("results-first") order:
//        for each user m of n:
//            for each r in height_maps[m].keys:
//                height_maps[n][r] := max(height_maps[n][r], height_maps[m][r]+1)
//
// Jump-Distance(n,m,height_maps):
//     Inputs: n (source node), m (destination node), height_maps (pre-computed above)
//     Output: jump_distance: int
//
//     jump_distance := 0
//
//     for each r in height_maps[n].keys:
//         if r is in height_maps[m].keys:
//             jump_distance := max(jump_distance, abs(height_maps[n][r] - height_maps[m][r]))
//
// Later on, if E is an edge from n to m, and Jump-Distance(n,m,height_map) > K (where K is kind
// of arbitrary but currently set to 20), we will "cut" the edge as illustrated above.
//
// -----------------
//
// The second tweak aims to eliminate routing pressure from nodes that have large outdegree and
// are connected to many otherwise-distant places in the graph. For this, the only thing we are
// doing at the moment is to "float" Parameter and Constant nodes. This means that rather than
// visualizing them as a single node (which might have very large outdegree as in, e.g., a
// learning rate parameter being fed to many different places), we make a "copy" of the node at
// each occurrence site (with a dashed outline).
//
// NOTE: This tweak could probably be extended to float other kinds of nodes with high out-degree.
// (This situation is likely to arise after constant subexpression elimination.) Here one has to
// be careful to avoid splitting the components. I have some rough ideas on how this could be
// dealt with, but have not had time to implement them yet. --amprocte
