  abstract =     "Genetic programming (GP) has been used to discover the
                 function that describes the collisions of positrons
                 with sodium, potassium, rubidium and caesium atoms at
                 low and intermediate energies. The GP has been running
                 based on experimental data of the total collisional
                 cross sections to produce the total cross sections for
                 each target atom. The incident energy and the static
                 dipole polarisability of the alkali target atom have
                 been used as input variables to find the discovered
                 function. The experimental, calculated and predicted
                 total collisional cross sections are compared. The
                 discovered function shows a good match to the
                 experimental data. We find that the GP technique is
                 able to improve upon more traditional methods. To our
                 knowledge, this is the first application of the GP
                 technique to the data of positron collisions with
                 alkali atoms at low and intermediate energies.",
