We utilize the situation calculus to develop a logical model of hypertext systems. The work builds upon the earlier work of Bieber and Kimbrough in the logical modeling of hyperte...
This paper presents an overview of the DIME environment (DIrect Manipulation Environment) being developed by the author. The paper presents the DIME vision, its catalogue of evolu...
Data structures with a hole, in other words data structures with an uninitialized field, are useful to write efficient programs: they enable us to construct functional data stru...
This paper presents a model of change propagation during software maintenance and evolution. Change propagation is modeled as a sequence of snapshots, where each snapshot represen...
In the running of a genetic algorithm, the population is liable to be con ned in the local optimum, that is the metastable state, making an equilibrium. It is known that, after a l...
