TY - CHAP A1 - Möller, Bernhard A2 - Bird, Richard T1 - Calculating with pointer structures T2 - Algorithmic languages and calculi: IFIP TC2 WG2.1 International Workshop on Algorithmic Languages and Calculi 17 - 22 February 1997, Alsace, France N2 - Based on the algebra of relations and maps we present some techniques for safe manipulation of pointer structures, with a special emphasis on tree-like structures. We investigate sufficient criteria for preservation of substructures under selective updating. The approach is illustrated with some simple examples.
