In this thesis, we develop and implement an efficient algorithm that can exactly solve instances of the mixed-integer programming problem that are given by rational data. For a feasible instance, a truly optimal solution will be computed; for an infeasible instance, a provably correct infeasibility certificate will be issued. Our exact mixed-integer programming solver is part of the constraint integer programming software SCIP, which is developed and maintained at the Zuse Institute Berlin. Mixed-integer programming solvers have experienced tremendous progress in the last decades, while almost no attention has been paid to exact computations. Most mixed-integer programming solvers, in particular, the state-of-the-art ones CPLEX, Gurobi, ...
