Introduction

We adopted the process of Reverse Engineering which in our work means to enumerate all possible network topologies and analyzed whether they fit the objection function or not, thus getting the right topology.
Here we chose the object function as Input-Output Alignment. In order to define IOA precisely for need of calculation, we considered most important characters of IOA and adopted Pearson Correlation Coefficient r to represent Input-Output Linear Relationship in the overall search work ( when r>0.99 we consider the network topology having the IOA function ), and also, regulated two levels for the initial and ultimate output concentration for the second character – the output range in further search work.(Figure 1)

Figure 1 Factors for selection of IOA network topologies. r is the Pearson Correlation Coefficient and the output range is HIGHLEVEL minus LOWLEVEL.

Calculating Process

In this part, we will demostrate our calculating process in three sections--Network enumeration, Equations set up and network topologies’ analysis.

Analyses and Results

As we search for proper network in two ways: linear and semilog, this part is divided into two sections -- linear and semilog.
