Jodici solver: Python vs Prolog

Jodici example

Jodici is a fun and intuitive number placement puzzle. It consists of a circle which a) contains 3 nested rings and b) is divided into 6 cake-piece-like sectors. As with Sudoku, the goal is to fill in all numbers, while satisfying certain rules: each field must contain an integer [1,9], with each such integer being used twice in total. Further, each sector sums up to 15 and each ring to 30.

Flower disk rotation puzzle solver: Python vs Prolog

The flower disk rotation puzzle consists of 4 wooden, stacked disks. The disks are connected at their center via a pole, so that they can be rotated. Each disk contains holes that are arranged around the disk center in the form of a flower. The holes are uniformly spread, so that there is space for 12 holes - but each disk only has 9 of these 12 possible holes (the position of holes differ per disk). The remaining 3 areas are instead made of solid wood. The goal is to rotate the disks so that all holes are covered by at least one of the disks (as we have a total amount of 4*3=12 solid areas for a total of 12 holes, each solid area must cover exactly one hole).
