    10. Assessment

    In the semester: two midterm. The condition for the audit is that both midterms are succesful.

    11. Recaps According to the general rules: one midterm can be repeated.
    12. Consultations According to demand
    13. References, textbooks and resources

    R. Diestel: Graph Theory (online available)

    J.A. Bondy & U.S.R. Murty: Graph Theory with Applications
