A. Lloris et al., USING DECISION TREES FOR THE MINIMIZATION OF MULTIPLE-VALUED FUNCTIONS, International journal of electronics, 75(6), 1993, pp. 1035-1041
This paper presents a simple procedure for the approximate minimizatio
n of multiple-valued functions using multiple-valued decision trees. T
he proposed procedure is compared with a near-absolute procedure, usin
g for the test four-valued functions of four variables. The results sh
ow a great advantage for our procedure with respect to the CPU time ne
eded.
