Question

You are an architect who needs to decide how to position four new shops in a mall: a Japanese restaurant, a hairstylist, a clothing store, and a toy store. The floor plan can be represented as 3 times 3 grid (three rows 0, 1, 2 and three columns 0, 1, 2) and you need to place each shop in one cell of the grid (row, column). Marketing research has generated the following constraints on how to position the shops. Note that establishments are considered close to each other if they share an edge on the grid. There is a fish and chips stand in cell (2, 2). There is a health store in cell (1, 0). The hairstylist and the clothing store should not be close to the fish and chips stand The Japanese restaurant should be close to the health store. The hairstylist and the clothing store should be close to the Japanese restaurant The hairstylist and the clothing store should not be close to the toy store Represent this problem as a CSP. Be as precise as you can in specifying the constraints. Also do not forget some basic constraints that are inherent in allocating objects in space but are not listed above.
