    Automatic solution of optimum design problems on a digital computer
    (Australian Atomic Energy Commission, 1962-03) Lawrence, BR
    A description is given of a method suitable for the automatic solution of certain optimum design problems on a digital computer for cases where the number of constraints imposed on the design is not greater than the number of design variables. The problem is transformed to one requiring the minimisation or maximisation of an unconstrained function, for which a gradient method is used.

    A basis for the computation of the energy dependence of the neutron flux and slowing down density in a bare reactor
    (Australian Atomic Energy Commission, 1963-09) Lawrence, BR
    A method is described for the computation of the energy dependence of the neutron flux and slowing down density in a bare reactor to form the basis of a 7090 Fortran computer program for survey studies of power reactors. Allowance is made for resonance absorption and resonance fission, neutron thermalisation, fast neutron reactions including (n, 2n) and (n, n), and anisotropic elastic scattering.
