    ...In this work we present a novel methodology that produces additional Pareto optimal solutions from a Pareto optimal set obtained at the end run of any multi-objective optimization algorithm. This method, which we refer to as Pareto estimation, is tested against a set of 2 and 3-objective test problems and a 3-objective portfolio optimization problem to illustrate its' utility for a real-world problem.

    Hanoi in Basic

    The Famous Recursive Algorithm In Old-Fashioned BASIC

    This program is written in BWBasic, the version provided with DOSEMU, the DOS emulator. In this version of BASIC, you use GOSUB to call a procedure, and there are no local variables. So I used arrays to allocate memory for stacks, from where the "local variables" are taken. From this code you can learn how recursion and functions with dynamic local variables work.

    Clusterfit

    Show stellar evolution and open clusters in a color-magnitude diagram

    ...In addition, it can show the CMD of a large number of existing open clusters, based on scientific survey data, and overlay isochrones (the curve in a CMD from stars born at the same time) to determine the age, distance and interstellar reddening of the cluster. Determining these parameters can be done automatically with a global search algorithm (more specifically a genetic algorithm). This program requires the installation of the libfgen package, also available on SourceForge.

    Griso is a graph isomorphism testing utility written in C++. It is based on my own POLYNOMIAL-TIME (in this point the salt of the project) algorithm. See Griso's sample input/output on http://funkybee.narod.ru/graphs.htm page. Edit (2012-10-24): seems so far it works for *regular graphs only* and should be tested on such graphs. Edit (2012-10-25): see two counterexamples in README.txt. But yet if Griso's verdict is "NON-isomorphic" it's 100% correct, so you can still make use of it. ...

    csg.js

    Constructive solid geometry on meshes using BSP trees in JavaScript

    ...With CSG, you build complex 3D shapes by combining primitives using Boolean operations like union, subtract, and intersect. The library focuses on clarity and correctness: its implementation is intentionally concise and readable so developers can understand the algorithm, while still correctly handling tricky edge cases such as overlapping coplanar polygons. A WebGL-based demo shows how two solids can be combined interactively in the browser, making it a great educational tool for learning CSG concepts. The API allows you to create primitives (cubes, spheres, etc.) and then combine or transform them programmatically, producing new mesh geometry for rendering or export. ...

    Averaged N-Dependence Estimators - AnDE

    AnDE implements A1DE and A2DE

    Averaged N-Dependence Estimators (A1DE and A2DE) achieves highly accurate classification by averaging over all of a small space of alternative naive-Bayes-like models that have weaker (and hence less detrimental) independence assumptions than naive Bayes. The resulting algorithm is computationally efficient while delivering highly accurate classification on many learning tasks. For more information, see, G. Webb, J. Boughton, Z. Wang (2005). Not So Naive Bayes: Aggregating One-Dependence Estimators. Machine Learning. 58(1):5-24 and G.I. Webb, J. Boughton, F. Zheng, K.M. Ting and H. Salem (2012).

    Exact Subgraph Matching Algorithm

    Exact Subgraph Matching Algorithm for Dependency Graphs

    The subgraph matching problem (subgraph isomorphism) is NP-complete. We designed a simple exact subgraph matching (ESM) algorithm for dependency graphs using a backtracking approach. The total worst-case algorithm complexity is O(n^2 * k^n) where n is the number of vertices and k is the vertex degree. We have demonstrated the successful usage of our algorithm in three biomedical relation and event extraction applications: BioNLP 2011 shared tasks on event extraction, Protein-Residue association detection and Protein-Protein interaction identification. ...

    Client Side Login Authentication Helper

    The project is to do pre-check of password before sending to server

    ...The purpose of the project is to capture and address unintentional human errors that could be resolved at the client side during the login process. Solution Abstract: An array of images are loaded at the client side. One of the images is displayed for every password entered based on a simple algorithm. The image is computed based on the password and hence it will change only when the user changes his password. Hence, the displayed image will become familiar to the user until he changes the password. It helps the user understand whether he input the right password before sending it to the server. This would be of great help in highly busy servers like stock-market and bandwidth challenged networks such as mobile data networks and dial-up networks.

Thus given an input (TXT) text file of any number of fundamental transversals, it will produce an output (CGD) text file of the resulting crystal nets. The algorithm applies point group symmetries to partial vertex figures of a fundamental transversal of a crystal net , and to the resulting images of those figures, to generate a unit cell of the net along with associated lattice vectors. This is a very preliminary version (Version 0.8) and consequently both unfriendly and limited. It consists of several interlocking Python worksheets. ...
