%description
Bayesian network learning using the PCHC, FEDHC, MMHC and variants of
these algorithms. PCHC stands for PC Hill-Climbing, a new hybrid algorithm
that uses PC to construct the skeleton of the BN and then applies the
Hill-Climbing greedy search. More algorithms and variants have been added,
such as MMHC, FEDHC, and the Tabu search variants, PCTABU, MMTABU and
FEDTABU. The relevant papers are: a) Tsagris M. (2021). "A new scalable
Bayesian network learning algorithm with applications to economics".
Computational Economics, 57(1): 341-367. <doi:10.1007/s10614-020-10065-7>.
b) Tsagris M. (2022). "The FEDHC Bayesian Network Learning Algorithm".
