Important updates (Mar. 13th & 9th):

Please only submit your solutions based on the newest version:

• Mar. 13th: The C99 code of problem m106 has been replaced.
• Mar. 9th: The C99 code of all problems has been replaced.

---

The problems are divided into two categories: Arithmetic and Data Structures. In contrast to the first category, the second one also features arrays in the source code. Achievements can be earned separately in each of these two categories.

Note that these problems cannot be compiled as downloaded because of a missing implementation of the __VERIFIER_error(int). Please read the Java-code and C99-code description for compilation assistance.

Other useful information can be found on the problem description page. The rewards page explains the corresponding ranking and achievements as well as available prizes. Training problems with solutions can be downloaded in order to test an approach before submitting to the challenge.

The following files are contained in each problem's directory:

• .java file: Java version of the source code.
• .c file: C99 version of the source code.
• "...alphabet_mapping_C_version.txt" file: Bijection between the integer values in the C99 version and the input/output symbols in the Java file.
• .traces file: Execution logs provided by ASML. See the problem description for details.

The problems are provided as a .zip archive.
