So, do you have any idea how much I can trust this this function (the version before you made it right)? I'm trying to Boyer-Myrvold in C++ and I wanted to use Sage for checking output of my program. |
2015-03-24 13:57:56 +0200 | commented answer | Testing planarity on embedding gives wrong result Thanks! This was the second time I used Sage for planarity testing, so I thought it was rather my mistake. By the way, why were the computations run on cached embedding, instead of mine? (I did't get from the report) |

2015-03-24 12:19:41 +0200 | asked a question | Testing planarity on embedding gives wrong result Hi, i've got planar embedding of K_4 which is not planar, but when I test it with is_planar(on_embeding=emb), it says that it is planar. Code: So, what am I doing wrong? |
