Symmetry and Symmetry Breaking in Software Patterns
Software patterns draw on the work of the architect Christopher Alexander, which in turn builds on foundations that may be more suitable to software than the architectural metaphors themselves. Patterns have a longstanding identity in the scientific community as results of a phenomenon called symmetry breaking. Symmetry breaking can be defined formally in terms of group theory. We establish for...
متن کاملSymmetry, Symmetry Breaking and Topology
The ground state of a system with symmetry can be described by a group G. This symmetry groupG can be discrete or continuous. Thus for a crystalG is a finite group while for the vacuum state of a grand unified theory G is a continuous Lie group. The ground state symmetry described by G can change spontaneously from G to one of its subgroups H as the external parameters of the system are modifie...
متن کاملSymmetry and Symmetry Breaking in Electrostatic MEMS
The use of electrostatic forces to provide actuation is a method of central importance in microelectromechanical systems (MEMS) and is of growing importance in nanoelectromechanical systems (NEMS). The study of electrostatic actuation has led to numerous interesting experimental, theoretical, and numerical results. Yet, surprisingly, even simple electrostatically actuated systems have secrets t...

متن کاملSymmetry Breaking
Symmetry occurs in many problems in aritifical intelligence. For example, in the n-queens problem, the chessboard can be rotated 90◦. As a second example, several machines in a factory might have the same capacity. In a production schedule, we might therefore be able to swap the jobs on machines with the same capacity. As a third example, two people within a company might have the same skills. ...
