- steep
- License: Freeware

This m-file provides a simple and efficient optimization method based on statistical design of experiments by the steepest ascent/descent procedure to predict points headed (hopefully) toward to optimum (maximum or minimum) for a first-order design. Inputs: B - vector of regression coefficients (parameters) of the fitted linear equation (first order): [intercept (1), linear (p)]. It must to be enter in that strictly order. V - vector of the factor values at starting point (current factor setting).

- Steepest Descent Algorithm
- License: Freeware

This is a small example code for "Steepest Descent Algorithm". It implements steepest descent Algorithm with optimum step size computation at each step. The code uses a 2x2 correlation matrix and solves the Normal equation for Weiner filter iteratively. Reference: Adaptive Filter Theory 3rd Edition Simon Haykin.

- Heuristic Algorithm for finding Maximum Independent Set
- License: Freeware

findMIS is an heuristic algorithm for solving Maximum Independent Set problem (MIS). An independent set of a graph is a subset of vertices in which no two vertices are adjacent. Given a set of vertices, the maximum independent set problem calls for finding the independent set of maximum cardinality. Algorithm run in O(n^2) time, where n is the number of vertices (worst case). Experimentally: time = 8.1e-007*n^2 + 2.2e-005*n + 0.00012 seconds, (see screenshot) The algorithm has been independently developped but is similar to: Balaji, Swaminathan, Kannan, "A Simple Algorithm to Optimize Maximum Independent Set", Advanced Modeling and Optimization, Volume 12, Number 1, 2010 Notation: The neighborhood of v is defined by N(v) ={u in V such that u is adjacent to v} The DEGREE of a vertex v in V, denoted by deg(v) and is defined by the...

- Steepest descent method
- License: Freeware

The script steepestdescent.m optimizes a general multi variable real valued function using steepest descent method. During the iterations if optimum step length is not possible then it takes a fixed step length as 0.001. For the theory any good book on optimization techniques can be consulted. This script is also useful in checking whether a given function is convex or concave and hence globally optimizable..

- Maximum Cardinality matching
- License: Freeware

If you use this code please kindly cite the following paper "Structure induction by lossless graph compression" Leonid Peshkin, In Proc. of Data Compression Conf. DCC , 2007 [mate] = card_match(adj) constructs a (Non-weighted) maximum cardinality matching on a graph represented by ADJ-acency matrix with edge IDs as elements OUTPUT: mate(i) = j means edge (i,j)=(j,i) belongs to the matching. REMARKs: a vertex _v_ is called "outer" when there is an alternating path from _v_ to an unmatched vertex _u_ that starts with a matched edge.

- Box Plot with Whiskers Plotted at Fixed Percentiles
- License: Freeware

Normally boxplot plots the whiskers with a maximum length based on the distance between the 25th and 75th percentile. This script uses boxplot but plots the whiskers for a specified percentile and only plots the outliers beyond the new whiskers. Note that the percentile is defined as the data point just beyond the calculated percentile. For example, if the 98th percentile lies between the 4th and 5th highest data points, then the 4th highest data point will be considered the 98th percentile, the whisker will extend to the 4th highest, and only the 4 highest values will be plotted as outliers.

In the one point-system, we suppose a optimum tetrahedral volume and this volume should be contain maximum points in the selected point-system. Extarly, this tetrahedral volume's of boundary conditions should be depend only four-node in point-system. Also, this sub-program running of similarly cyclic-permutation technique than not more-speedly. This program's cyclic-permutation run-time is depend matlab main function as -nchoosek-. Plainly, If you selected more 50 point than solution time possible be few minute.

- plot_feasible.m
- License: Freeware

plot_feasible(A, b, c, lower_b, upper_b, varargin) Plots the feasible region of the 2D linear program maximize f = c'*x subject to A x <= b on the region bounded by lower_b and upper_b. It can plot the region, bounding lines, their intersection points and vertices of the feasible region along with the maximum. Its primary use (for me) is for students learning Linear Algebra. Its has lots of options for making the plot look pretty, or annotating vertices, etc. And you can put iso-objective function lines across the plot to help.
