Question

Problem 3 A labeled transition system (LTS) M is a triple (S, A, where S is a set (finite or infinite) of states, A is a finite set of actions, and is a ternary relation over S x A x S. If the argument of is (si, a, 8 e S x A x S, we write "si si" instead of (si, a, s i) We assume that the states in S are indexed with a set I of natural numbers, i.e., S si i E I t. If S is finite with S n, then I is the initial segment 10, 1 nt of N; if S is infinite, then I N. If we write s si, we mean that the LTS M can make a transition from state si to state si when action a is applied. The set of next states from si with action a is defined by: next si, a 81 ESI si 8 If next(si, a) then M cannot make a transition from state si with action a. We write next (si) to denote UaeA next(si, a), which is the set of all next states from 8 Caution: The relation in M, which is called the transition relation of M, is unrelated to logical implication The symbol is overloaded (sorry!).

Explanation / Answer

Avoid structural changes as far as possible, such as changing the default set of applications, lots of library transitions, or system layer changes (example: introducing KMS or hal DeviceKit would not have been appropriate changes in a LTS).

Furthermore, we define the LTS to be:

Enterprise Focused: We are targeting server and multiple desktop installations, where the average user is moderately risk averse.

Compatible with New Hardware: We will make point releases throughout the development cycle to provide functional support for new server and desktop hardware.

More Tested: We will shorten the development window and extend the Beta cycle to allow for more testing and bug fixing

and clearly state that it is not:

A Feature-Based Release: We will focus on hardening functionality of existing features, versus introducing new ones1, except for in the areas of Online Services and Desktop Experience2.

1. Exceptions for priority projects will be documented.
2. Because these two areas of development are relatively new, they still require new features to satisfy the original reasons for their creation
