MATSim Code

create a class to iterate the model to calibrate "thresholds"

this corresponds to the "manual calibration" of the paper. Instead that
I do not want to manually calibrate anything.

use log( dist + 1 ) instead of log( dist ) in utility

otherwise, utility of being friend with somebody living in the same
building is infinite. Distance usually being expressed in meter, this
should not change much to the results for friends living farther than
one meter away... This should be tested, though.

much faster secondary tie search

average personal network size

allow egos without ties

"utils" class to produce sna statistics

add a test of reciprocity

change in removeRandomMapping

"script" for Arentze's TRB paper model

make Agent a marker interface and let attribute getters be defined by implementations

this is called so often that it really makes a huge difference to store
attributes in a map or directly. All classes using Agent are made
generic, so that the required implementation can be used without casts.
