Salut et Fraternité vs SimplexLP

Conversion software between the gregorian calendar and the republican calendar. Created during the french revolution, the republican calendar had 12 months of 30 days, followed by 5 or 6 complementary days. It was legal in France from 1793 to 1806. Each day was associated to a plant, an animal or a tool. The app gives too the decimal time: the cientists wanted to change our way to measure the time in the day, each one being divided in 10 hours of 100 minutes of 100 seconds. By double tapping the screen Today, you can send messages with the republican date by mail or in Facebook or Twitter, etc.. N.B.: Facebook does not allow the perfil of the posts. But in the app, you can copy the date, to manually paste it in the Facebook post.

SimplexLP solves linear optimization problems, which can be mathematically described with an objective function and a set of constraints. With the new graphical representation (possible with 2 variables only) it is a lot easier to understand the theoretical concept of linear optimization! SimplexLP is the perfect learning companion for teachers (to set up problems) and students (to learn the Simplex algorithm). It is very easy to change coefficients and see how the solution varies. For the calculation the famous Simplex algorithm is used. With SimplexLP you can: – easily set up the objective function and the constraints; – solve maximization and minimization problems; – solve problems with unlimited number of variables and constraints; – solve problems with ≤, ≥ and = (in)equalities; – get all the possible solutions ("edges") to a problem; – get accurate calculations with fractions; – get your output in fractions or decimal values; – set a fixed value in the objective function, e.g. for fixed costs; – set the tab width (via a simple swipe gesture) to format the tableaus; – get a graphical representation of optimization problems with 2 variables. With SimplexLP linear optimization really makes fun!
