Karger's Algorithm - Running Time - Edge Contraction

In Karger's Min-Cut Algorithm for undirected (possibly weighted) multigraphs, the main operation is to contract a randomly chosen edge and merge it's incident vertices into one metavertex. This process is repeated until two vertices remain. These…

I don't understand why my python code for random contraction algorithm return None type

I have written python code for doing random contranction algorithm, the problem I ran into is that the return of this function is None type. However, for each recurrence, I can print out the result. so I don't have a clue why this is…

Efficient tensor contractions by BLAS

C[a,d,e] = A[a,b,c] * B[d,b,c,e] The topic is relate to BLAS tensor contractions for two indexes together , but more complicated. I can only use do loop to call gemm for many times. The data structure of C and B is not contiguous in current…

BLAS tensor contractions for two indexes together

I want to calculate D[a,d] = A[a,b,c] * B[b,c,d]. Method I: reshape A[a,b,c] => C1[a,e], B[b,c,d] => C2[e,d], e = b*c Method II: directly call dgemm. This is a run-time error. " na, nb, nc, nd ? 2 3 5 7 Time for reshaping method …

What is fast way do a tensor contraction for two indexes by BLAS(dgemm)?

I want to calculate tensor contraction. X[a,b,e] = Y[a,b,c,d] * Z[c,d,e] Here, I want to contract two indexes c and d together. My idea is: reshape Y=[a,b,c,d] ==> Y[a,b,m] , m=c*d; Z[c,d,e] ==> Z[m,e] X = dgmm(Y,Z) Reshaping costs some time. Is…
