The most promising way to solve QCD is given by numerical simulations using Markov Chain Monte Carlo (MCMC) Methods, in which the space-time continuum is replaced by a lattice.
We shall demonstrate that since the
invention of this approach by K. Wilson the conceptual, algorithmic and
supercomputer developments have progressed so much that today realistic
simulations of lattice-QCD become possible, bringing us close to a, at
least, numerical solution of QCD. As some examples, we will show results
for the hadron spectrum, resonances and the structure of nucleon. We
will also discuss open problems, in particular those where MCMC methods
are not applicable and where tensor network techniques have a strong
potential to make substantial progress.
