Computation with multiple CTCs of fixed length and width, A. C. C. Say, A. Yakaryilmaz. Natural Computing, Vol. 11, No. 4, pp. 579-594, 2012. DOI

ERRATA: On Page 14: Theorem 10: The expected runtime should be 28. At the end of the proof, the infinite sum should be
$ 1 + \frac{1}{2} \cdot 2 + \frac{1}{4} \cdot 3+\frac{1}{8} \cdot 4+ \cdots = 4. $
