N2 - Abstract: The results of operation of the EPOS4 and URQMD 3.4 (LHC) event generators were compared by the example of simulation of pp-collisions at ultrahigh energies (7 TeV). Violation of the laws of conservation of baryon and lepton charges and conservation of energy in EPOS4 was shown. A comparison with experimental data was made, and the influence of event filtering by conservation of energy and baryon and lepton charges on the multiplicity distribution in the pseudorapidity range |η| ≤ 1.5 was studied.
