semi-definite programming for the recovery of stochastic block model

SBMSDP2

This repository uses semi-definite programming to recover labels of stochastic block model.

Note

The code in this repository can only recover symmetric SBM with two underlining communities. Symmetric SBM means that the two communities have equal size.

The SBM generator is $\text{SBM}(n,\frac{a\log n}{n},\frac{b\log n}{n})$.

Sample code

from sbmsdp import sbm2, sdp2
G = sbm2(100, 16, 4)
X = sdp2(G)
print(X)
