iSolveModel4.1

Looking for a mathematical model solver running on your iPad/iPhone/iPod Touch? This is iSolveModel, an easy-to-use linear programming optimizer running on iPad as well as on iPhone and using the simplex algorithm method with pivot as the main solver engine as well as an integrated MIP solver for 0-1 variables and integer numbers. The purpose of this application is to provide a linear programming solver for the iPad/iPhone/iPod Touch community as well as for students and teachers, particularly for those in Operations Research / Operations Management / Industrial Engineering or related courses (college/undergraduate students).

Features:
- Number of decision variables and constraints only limited by the available memory of the device
- Sensitivity analysis reports on variable coefficients and right-hand side when solving pure linear models
- Documents can be transferred via iTunes File Sharing
- Mathematical models and solutions can be sent by email
- Model documents are text files, no proprietary format
- Solution documents as HTML
- Supports all device orientations

Benefits:
- Affordable
- Easy-to-use modeling, models are like the ones in textbooks
- Fast learning curve
