SimplexLP vs DGKS

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!

The official app for the Congress of the Association of Structural Engineers of Serbia (DGKS), held 23–26 September 2026 at the Grand&Sky Hotel Tornik on Zlatibor. The full programme, everyone taking part, and every floor plan — in your pocket, in Serbian or English, with or without a connection. A PROGRAMME THAT STAYS CURRENT Browse all four congress days session by session: time, hall, chairs, and every presentation inside a session with its authors and speakers. Changes made to the official programme reach the app on their own. WHAT IS ON RIGHT NOW The home screen shows the sessions running at this moment, how long each has left, and what follows in the same hall. If the coffee break ran long, the app knows where to send you back. MY AGENDA Bookmark the sessions and presentations you do not want to miss and keep them in one place. Any session can go into your phone calendar in a single tap, with a reminder 15 minutes ahead. NOTES Write a note against any session while it runs. Notes stay on your device and are sent nowhere. PEOPLE AND PAPERS Search authors, speakers and chairs, open a profile with their affiliation and list of papers, or start from a paper and reach everyone behind it. One search covers people, papers and institutions at once. PARTNERS AND EXHIBITORS Partner and exhibitor profiles with stand numbers and their position on the hall plan, so you know exactly where to find them. MAPS AND VENUE Floor plans for the halls and the exhibition area, plus a venue map with directions handed off to the maps app you already use. NOTIFICATIONS Announcements from the organisers about programme changes, added sessions and deadlines — in the language you picked in the app. SURVEYS Fill in the organisers' surveys straight from the app, while the session is still fresh. WORKS WITHOUT A CONNECTION Content is stored on your device on first launch. When the hall Wi-Fi gives up, the programme, the participants and the maps are still there. TWO LANGUAGES, TWO THEMES Serbian and English, switched in one tap. Light and dark follow your phone's setting. NO ACCOUNT No sign-up, no password, no charge. Install it and use it.
