Instructions: answer these questions;
1. Introduce backward search and forward search in H_OSTP model (Guanfeng's paper published in SCC2010). Why to have both search processes in the attempt to identifying an optimal trust path?
2. Study Haibin's paper published in TrustCom2012, and explain why to compute a set of the trust values of a seller in a forthcoming transaction. Introduce the general idea of the proposed algorithm.

Backward search and forward search in H_OSTP model(Guanfeng's paper published in SCC2010)
Backward Search refers to a problem solving technique undertaken by the solver by working from the goal to the beginning. Similarly, forward search algorithm is solving a problem from the beginning with a desired goal in mind.
H_OSTP first takes into consideration the Backward Search in a bid to find out whether there is a practical solution between the target and the source, if a solution is found and aggregate Quality-of-Trust recorded then Forward Search procedure is taken up to implement the optimal procedure.
