S. Brunetti et al., On the computational complexity of reconstructing three-dimensional lattice sets from their two-dimensional X-rays, LIN ALG APP, 339, 2001, pp. 59-73
A generalization of a classical discrete tomography problem is considered:
reconstruct three-dimensional lattice sets from their two-dimensional X-ray
s parallel to three coordinate planes. First, we prove that this reconstruc
tion problem is NP-hard. Then we propose some greedy algorithms that provid
e approximate solutions of the problem. (C) 2001 Elsevier Science Inc. All
