Nature of problem:
Solution of the QCD evolution equations for the parton momentum distributions of the DGLAP- and modified-DGLAP-type in the LO and NLO approximations.

Solution method:
Monte Carlo simulation of the Markovian process of a multiple emission of partons.

  1. Limited to the case of massless partons.
  2. Implemented in the LO and NLO approximations only.
  3. Weighted events only.

Unusual features:
Modified-DGLAP evolutions included up to the NLO level.

Additional comments:
Technical precision established at 5 x 10-4

Running time:
For the 106 events at 100 GeV: DGLAP NLO: 27s; C'-type modified DGLAP NLO: 150s (MacBook Pro with Mac OS X v.10.5.5, 2.4 GHz Intel Core 2 Duo, gcc 4.2.4, single thread)
