Answers to Questions

What is a convering design? (Definition)

Covering Designs are a technique for optimizing bets for drawing games (Lottery, Lotto-like, Powerball, Euromillions, etc.). The principle is to combine several games / grids that minimize bets to ensure a minimum win each game.

Example: dCode proposes a system of 130 grids which certify a gain of 2 guaranteed minimum numbers guaranteed for 100% of the draws at the Euromillions (draw of 5 among 50 numbers)

How to generate a reduced system/covering design?

The generation of covering designs uses combinatorial calculation tools such as the combinations generation. Calculations are very greedy and still require several days today to find solutions.

dCode can generate some systems quickly thanks to several series of pre-computed cover designs that are optimal but also other non-optimal designs (but whose computer calculations have not yet found better solutions here (link) ).
