Keywords: Elementary, Particle physics, Monte carlo generation, Quantum chromodynamics, Function structure Evolution, Leading logarithm Approximation, Next to leading Logarithm approximation, Heavy quark effects.
Classification: 11.5.

Nature of problem:
Calculation of QCD evolution of structure functions including next to leading order effects with the immediate aim of determining relevant QCD parameters by least-square fits to experimental data.

Solution method:
Monte Carlo generation of the QCD emission of quanta.

Restrictions:
None in the leading log approximation. Only non-singlet analysis is implemented in the next to leading log approximation.

Unusual features:
Use of the CERN Program Library, and specifically of the minimization program MINUITS.
