Major Differences between Cosmos and Tierra

In this section the main areas in which Cosmos differs from Tierra are highlighted. A fuller explanation of why some of these differences were incorporated into the system can be found in [Taylor & Hallam 97]. In the following, the extension of standard Tierra to deal with parallel processes, as described in [Thearling & Ray 94] and [Thearling 94], is referred to as `Parallel Tierra'.
