Exact solutions of nonlinear partial differential equations (NPDEs) are obtained via the enhanced (G'/G)-expansion method. The method is subsequently applied to find exact solutions of the Drinfel'd-Sokolov-Wilson (DSW) equation and the (2+1)-dimensional Painlevé integrable Burgers (PIB) equation. The efficiency of this method for finding these exact(More)
Automated Study Planning (ASP) system was designed to assist the students in organising their studies. Interactive expert system ASP forms a part of a bigger project that concerns computer-based education and training in higher learning [1]. The formulation of the study-planning process, whereupon the reasoning engine of ASP is built, has been acquired from(More)
New methods of automating design generation differ greatly from the ways AI researchers have attempted to elicitate and implement design knowledge. The latter tradition is coined by the so called 'knowledge based approaches'. A good example for floor plan design can be found in (Zandi 1992). Using iterative algorithms (e.g. artificial neural networks), this(More)
