MATSim Code

Added analysis class for finding consecutive activities at the same facility.

FINALLY fix those stupid tests!!!

problem seemed to be with empty routes, where (for some reason), the old
semantics of the agent lead to leaving the start-and-end-link...

util.random moved to DVRP; VehicleGenerator fixed

some more refining of Ids and shuffling of myScenarioLoader

transform problem into a mono-objective one

also write to file whether step was improving

only one initial value

more configurable

less initial points

do not constrain secondary reduction to be positive

negative reductions might actually make sense, as sampling rate for
secondary round typically higher (threshold includes probability to
meet)
