Summary0000090: neato gives up on a graph. it asks me to fill this form
Description



neato gives up on the following graph without any more explanation
it works fine without the graph attribute model=circuit
it fails when this attribute is set
Additional Information

[erg] The cause is that something goes wrong during the solution of the
circuit model. neato reports this on stdout, lneato doesn't recognize a
graph and gives up.

The root cause is that the graph is disconnected. The circuit model inverts
the Laplacian, but this is singular for disconnected graphs.

A related problem is that, in this case, the user's graph wasn't really
disconnected. He uses a node 2810_admin, which the lexer breaks in two,
making the graph disconnected. The parser prints a warning but it doesn't
show up in lneato in Windows.
TagsNo tags attached.
