We discuss an approach to solve the sign problem based on deforming the region of integration in the path integral from real fields to a manifold in complex space. It generalizes the"Lefschetz thimble" approach that received much attention lately. We discuss principles through a simple geometrical picture, discuss algorithm features required to make the idea work and present examples in simple models ranging from 0+1 D fermionic models to 3+1D bosonic models and real time dynamics.
