NOTE: This application is currently is in beta and is should not be expected to be fully functional.

Simplex solve is a simple tool for solving linear programming problems using the Simplex algorithm. The app features a matrix or equation input format for convenience.

Usage:

1. After putting the linear programming problem in standard form, first enter the number of variables and constraints.

2. Next, choose an input method (matrix or equation) and a solve mode to find the minimum or maximum.

3. Input the problem.

3a. Matrix Input:

For matrix input, simply enter the coefficients of the variables, where the top row is the objective function coefficients and the rest of the rows are for constraint inputs.

3b. Equation input:

Enter the objective function, in the following format: Ax0+Bx1+Cx2...MXn where A B C...M are the coefficients. If the coefficient is 0, simply enter, for example, 0x1. The variable names MUST be x0, x1, x2....xn.

4. Press the solve button to solve the problem. The minimum/maximum will be displayed as well as the optimal value.

## Didactic Linear Programming

The aim of Didactic Linear Programming is to explain step by step the resolution of all kind of linear programming problem. In that goal, the following concepts have been implemented: primal problem, dual problem, post-optimisation, integer linear programming and graphical interpretation.

## WordStock : Vocabulary Builder

WordStock is a home screen widget, which helps in improving user’s vocabulary.

It displays certain number of random words repeatedly. Their meaning can be seen by tapping on them. Once the user feels that she has learnt that word, she can mark it as learnt. A new word will come up at that place.

## TagIT: Image Tagging Restated!

TagIT takes an image, and tags comments/info on different locations of that image.

The user can write some text, record audio or video or click a picture and tag it to the image.

When this image is opened, it highlights those regions for which tags are available and tapping on them, displays it.

The user can write some text, record audio or video or click a picture and tag it to the image.

When this image is opened, it highlights those regions for which tags are available and tapping on them, displays it.

This app will find special use in classrooms. During classroom lectures, we can click the image of the board in the starting, and then tag a particular part of it (with different media) which is being explained by the teacher. This app will reduce the length of the lectures because, in conventional recording of the lectures, the whole lecture is recorded and thus the unimportant things are also present. But here, only small & useful pieces of information will be tagged with text/audio/video/picture. Now, you can carry the notes in your pocket..

This app can also be used to review a photograph or attach some description to it with help of tagging.

Features

•Image can be taken from camera or chosen from gallery

•Image can also be used in the project while browsing the gallery by sharing it via TagIT.

•Image can be cropped as they are taken

•Tag type can be changed during the process of tagging by pressing menu key

•Tags can be moved within the canvas

•Tags can be made to disappear by tapping anywhere outside the image

•Tags can be deleted by long pressing on them

•Canvas image can be changed at any point, by pressing menu key

•Uses GPS to get the location where the project is being started

•Project name and location can be changed from the ‘existing project’ list

•Whole project can be shared via Bluetooth

•The receiver can’t modify the original project. For that, he/she has to import a copy of that project (by pressing menu key)

•The app also provides the facility to make text notes

•The text notes can be shared via different modes like Bluetooth, Gmail etc.

•All projects and notes can be sorted (by pressing menu key)

Please mail me for feedback and suggestions.

If the app doesn't work on your device then please let me know by email.
