Algorithms are presented for the optimisation of the luminosity in pp and /SUP p/ p colliders. Their average luminosity is lower than the peak luminosity because the transverse dimensions of the beams increase due to intra-beam scattering, and the beam currents decay due to the collisions with the rest gas and the opposite beam. Assuming that the /SUP p/ are produced during the collision time links the /SUP p/ production rate to the maximum /SUP p/ current. Either the average luminosity or the average number of collisions with exactly one beam-beam event are optimised. The free parameters are the collision time, the initial luminosity, and the density of the beams. Numerical solutions are based on the parameters of the /SUP p/ p option of the Large Hadron Collider (LHC) and on the /SUP p/ production rate of the /SUP p/ source (ACOL) at CERN. Approximate analytical solutions are also presented.
