question: public void testLocalInstances_distribution ( ) { MatsimRandom . reset ( 123L ) ; Random local1a = MatsimRandom . getLocalInstance ( ) ; double value1 = local1a . nextDouble ( ) ; MatsimRandom . reset ( 234L ) ; Random local2a = MatsimRandom . getLocalInstance ( ) ; double value2a = local2a . nextDouble ( ) ; Random local2b = MatsimRandom . getLocalInstance ( ) ; double value2b = local2b . nextDouble ( ) ; assertTrue ( Math . abs ( value1 - value2a ) > EPSILON ) ; assertTrue ( Math . abs ( value2a - value2b ) > EPSILON ) ; assertTrue ( Math . abs ( value1 - value2b ) > EPSILON ) ; }
target:  Tests that multiple local instance return different random numbers, and that they are more or less evenly distributed.
