  Considerable progress has recently been made in the development of techniques
to exactly determine two-point resistances in networks of various topologies.
In particular, two types of method have emerged. One is based on potentials and
the evaluation of eigenvalues and eigenvectors of the Laplacian matrix
associated with the network or its minors. The second method is based on a
recurrence relation associated with the distribution of currents in the
network. Here, these methods are compared and used to determine the resistance
distances between any two nodes of a network with topology of a hammock.
