Sequential diagnosis with aymmetrical tests,
The Computer Journal, Vol. 41, No. 3, 1998, pp. 163-170.

In this paper we present the generalization of the test sequencing problem, originally defined for symmetrical tests, that also covers asymmetrical tests. We prove that the same heuristics that has been employed in the traditional solution of the problem (e.g., the AO* algorithm with heuristics based on Huffman's coding) can be employed also for the generalized case. Examples are given to illustrate the approach.
