Graph-based Implementation of a Functional Logic Language H. Kuchen, R. Loogen, J.J. Moreno Navarro, M. Rodriguez Artalejo We investigate the development of a graph reduction machine for a higher-order functional logic language by extension of an appropriate architecture for purely functional languages. To execute logic programs the machine must be capable of performing unification and backtracking. We show the integration of these mechanisms in a programmed (functional) graph reduction machine. The new machine has been implemented on a transputer system.
