Abstract
There are several problems in theoretical physics which are defined by complex valued weight functions e(-S) where S can be a complex action or classical Hamiltonian. Complex Langevin is one method to simulate integrals over such complex valued weights. The conditions under which the so called complex Langevin process can be related to the complex weight and correctly simulates such integrals are discussed.
