Types of trees

A tree data structure is a non–linear structure that stores data hierarchically. It can be defined as a group of objects, called nodes. The nodes are linked with edges. Trees begin with a root node which leads to children nodes. The last children nodes (endpoints) are called leaf nodes, and they do not have children nodes.

2. Determine using a tree whether the following propositions are jointly satisfiable. If
they are, read off from your tree a model on which they are both true (and be sure to
indicate which path you are reading it off from).

Formal Methods are based on logic reasoning. Conceptually the two most common logics are propositional logic and Predicate Logic. An undergraduate student who took a course of discrete mathematics is inquiring as to how propositional and predicate logics can be used in software testing. You are asked to guide this student in this quest. One pointer may consist in presenting the characteristics and limitations of both logic as well as their use as a mean for software testing. Which Logic is most adequate for formal verification of software and how this should be implemented?
