For the sixth time in a row, I was a problem setter and judge for an ACM ICPC programming contest held in Ateneo de Naga University. Last October 7, 2018, twelve teams participated and their performances are shown below. I guess the low number of participants is due to the two-year absence of new undergraduate students (from 2016 to 2017) due to the addition of two years of senior high school in the Philippine educational system.

I contributed two problems: Problem C: “Symbolic System” (based on the symbolic system described on page 102 of Wolfram’s “A New Kind of Science”) and Problem E: “Fibonacci Ones digit” (based on Rossi D’Souza’s “Where did/do mathematical concepts come from?” in *For the Learning of Mathematics*, vol. 36, no. 1, pp. 25-27). Only two teams attempted problem C; only one team attempted problem E; all three failed to solve the problems.
