The direction identifies the next cell along the shortest path back to the closest source while avoiding barriers. The range of values is from 0 degrees to 360 degrees, with 0 reserved for the source cells.

path integral can then be pictured as originating in a Riemannian four-sphere. While rooted in the Euclidean approach, the path integral is then usually de ned by complex contour integration in order to identify the leading saddle point contributions, which cannot be characterised as purely Lorentzian or Riemannian [4].

Euclidean geometry. In this picture one speci es a state via a choice of contour of integration through the space of (appropriately complexi ed) metrics. We then need to understand which metrics contribute to the Euclidean path integral [4], and how this contour of integration can be constructed. In the original approach of Hartle
