    Source documentation

    Shrink both local domains before forming the global contact predicate. Every parameter of the entire retained graph, not just parameters in a later component ball, has both outer coordinates outside the fixed central ball.

    Source documentation

    Unconditional actual Coulomb supporting charts with graph-wide exclusion of both outer coordinates from a common fixed central neighborhood.
