Rocksolver builds a wall

Even before structural stability criteria have been explicitly programmed into Rocksolver it has built a stable structure. The photo shows Rocksolver's automatically generated design and the small desk-top structure built from real rocks following Rocksolver's plan. Rocksolver is using a 2D optimisation algorithm which would suit many applications such as retaining walls where stone masons already select prism-shaped rock. Stone masons mostly use a mental 2D algorithm to build a variety of structures from prism-shaped rocks because that's a lot easier than the mental 3D manipulations required to build with a random selection of rocks. Already Rocksolver has the capability to use 3D algorithms and build with random irregular shapes. Results from 3D testing will be published here and at intresto.com.au as they come to hand.
