Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagram, flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
Slate is a prototype-based object-oriented programming language based on Self, CLOS, and Smalltalk. Slate syntax is Smalltalk-80-based, rather than trying to be clever and complex. However, the language semantics, environment, and run-time design are all much more powerful than in traditional Smalltalk systems. The design goal is to bring together many excellent existing ideas into one system, and to provide an environment where design decisions in one area don't constrain others.
InformationSpace is a causal set exploration tool. A causal set is basically a set of simple rules that define the relationship between bits in a space time. A common example of this is John Conway's game of life. InformationSpace supports 3D space/time (2D of space, 1D of time). Visualization is in 3D, with Y being time.
Genetic Algorithm in Squeak is a genetic algorithm framework that implements the operation of selection, mutation, and crossing-over. Memetic-algorithm capabilities were added through an implementation of a local search based on hill climbing and dynamic hill climbing. Mutation operations are based on random gaussian-like distribution, so small adjustments are more likely than drastic ones. Selection is implemented with Tournament or with Roulette Wheel and Elite, in Roulette Wheel you can chose Sigma Fitness Scaling or Linear Fitness Scaling. The modelling capabilities of Smalltalk and the visualization an development capabilities of Squeak were exploited, and priorized in spite of the apparently low performance of both Smalltalk and Squeak.
