T. Yu et O. Kaser, A NOTE ON ON THE CONVERSION OF INDIRECT TO DIRECT RECURSION, ACM transactions on programming languages and systems, 19(6), 1997, pp. 1085-1087
In the article, ''On the Conversion of Indirect to Direct Recursion''
(ACM Lett. Program. Lang. 2, 1-4. pp. 151-164), a method was introduce
d to convert indirect to direct recursion. It was claimed that for any
call graph, there is a mutual-recursion elimination sequence if and o
nly if no strongly connected component contains two node-disjoint circ
uits. We first give a counterexample and then provide a correction.
