  abstract =     "n this paper, we propose a technique based on genetic
                 programming (GP) for meshfree solution of elliptic
                 partial differential equations. We employ the
                 least-squares collocation principle to define an
                 appropriate objective function, which is optimised
                 using GP. Two approaches are presented for the repair
                 of the symbolic expression for the field variables
                 evolved by the GP algorithm to ensure that the
                 governing equations as well as the boundary conditions
                 are satisfied. In the case of problems defined on
                 geometrically simple domains, we augment the solution
                 evolved by GP with additional terms, such that the
                 boundary conditions are satisfied by construction. To
                 satisfy the boundary conditions for geometrically
                 irregular domains, we combine the GP model with a
                 radial basis function network. We improve the
                 computational efficiency and accuracy of both
                 techniques with gradient boosting, a technique
                 originally developed by the machine learning community.
                 Numerical studies are presented for operator problems
                 on regular and irregular boundaries to illustrate the
                 performance of the proposed algorithms.",

                 This is a step towards an 'automated discovery engine'.
                 The automated analytical solution of partial
                 differential equations (which this paper proposes a
                 method for) is a 'blue sky' area at the moment, but has
                 the potential to yield unexpected physical insights
                 when applied to poorly understood 'real life'
                 problems.",
