python - Grouping Data into Clusters Based on DataFrame Columns -

i have dataframe (df) resembles following: a b 1 2 1 3 1 4 2 5 4 6 4 7 8 9 9 8 i add column determines related cluster based upon values in columns , b: a b c 1 2 1 3 1 4 2 5 3 1 3 2 4 6 4 7 8 9 b 9 8 b note since 1 (in a) related 2 (in b), , 2 (in a) related 5 (in b), these placed in same cluster. 8 (in a) related 9 (in b) , therefore placed in cluster. to sum up, how define clusters based upon pairwise connections pairs defined 2 columns in dataframe? you can view set consolidation problem (with each row describing set) or connected component problem (with each row describing edge between 2 nodes). afaik there's no native support this, although i've considered submitting pr adding utility tools. anyway, like: def consolidate(sets): # http://rosettacode.org/wiki/set_consolidation#python:_iterative setlist = [s s in sets if s] i, s1 in enum

continuous integration - Is it possible to trigger dependent job in Jenkins BEFORE main job starts? -

-
there few jobs: a , b , others. a depends b , i.e a job triggers b one, no vice versa. a , b cannot run simultaneously. so, problem jobs lock each other: a waits while b finished, when b can't start, because a started (is waiting completion of b ). is possible trigger b job before a job starts? up- , downstream features , found plugins can't solve issue. other jobs can start b job too. of jobs have not artifact dependencies. any ideas? try parameterized trigger plugin post build action -> trigger parametrized build on other project

java - Issues in Implementing Karger's Min Cut Algorithm using Union-Find -

-
i've implemented karger's algorithm using union-find datastructure using path-compression heuristics , union rank i've run couple of issues what i've done is, run algorithm n n log(n) time estimate of answer. however, don't answer mincut. pick random edge each time has 2 members source 's' , destination 'd'. if parents not equal, merge them , reduce count of vertices, 'vcnt' equal original number of vertices. process continues until number of vertices left 2. finally, find parent of source , destination of each edge , if ont equal, increase mincut count. repeats n n log(n) times. i've tried running code lot of test data don't seem getting mincut value, large data. could me out? also, performance improvement suggestions welcome. here code: import java.io.bufferedreader; import java.io.fileinputstream; import java.io.ioexception; import java.io.inputstreamreader; import java.util.arraylist; class kragersmincut { static
