Generators,A particle starts at time . = 0 at -1 ≤ . < 0, moving at speed +1 until it hits . = 0; at that moment, it begins a reflecting B.ian motion on [0, + ∞), stopping at the passage time m. to . = 1, waiting at that place for an exponential holding time e with mean and jumping at time m. + e to the point ∞.
