Graph Transversal Algorithm

Introduction

A graph transversal algorithm is a method used in computer science and network theory to traverse or search through a graph in a systematic way. In the context of exploring a Multinational Enterprise (MNE) shareholding structure, this algorithm becomes a powerful tool for understanding the intricate relationships and hierarchies within the company. This article discusses the application of graph transversal algorithms in analyzing MNE shareholding structures, supported by concrete numeric examples.

Understanding MNE Shareholding Structures

MNE shareholding structures can be complex, with multiple layers of ownership and control across different jurisdictions. These structures can be represented as directed graphs where nodes represent entities (like parent companies, subsidiaries, and joint ventures) and edges represent shareholding relationships.

Graph Transversal Algorithms

Graph transversal algorithms, like Depth-First Search (DFS) and Breadth-First Search (BFS), are used to explore these graphs.

• Depth-First Search (DFS): This algorithm starts at a root node and explores as far as possible along each branch before backtracking. It's useful for discovering the depth of control within an MNE.
• Breadth-First Search (BFS): This algorithm starts at the root node and explores the neighbor nodes first, before moving to the next level neighbors. BFS is efficient in identifying all entities directly or indirectly controlled by a parent company.

Example: Analyzing a Deep MNE Shareholding Structure

Let's consider a hypothetical MNE, 'FinGlobal', with a layered shareholding structure.

Graph Representation:

• Nodes: FinGlobal (parent), Subsidiary X, Y, Z, Sub-Subsidiary X1 (owned by X), Sub-Subsidiary Y1, Y2 (owned by Y)
• Edges: Represent shareholding relationships and percentages.

Using DFS for Inherited Characteristics:

insert DFS example

• The DFS path is shown in red. The traversal begins at 'FinGlobal', moves to 'Subsidiary X', and then proceeds to 'Sub-Subsidiary X1'. The numbers on the arrows indicate the sequence of the DFS exploration. This path demonstrates how DFS delves into each branch to its fullest depth before backtracking..
• It helps in understanding how characteristics like consolidation methods or legal statuses are inherited from FinGlobal down to Sub-Subsidiary X1.

Using BFS to Define a Real Sub-Tree:

insert DFS example

• Start at FinGlobal, covering Subsidiary X, Y, and Z.
• The next level includes Sub-Subsidiary X1 under X and Sub-Subsidiaries Y1 and Y2 under Y.
• This approach carves out a sub-tree under Subsidiary Y, comprising of Y itself and its subsidiaries Y1 and Y2, each potentially inheriting characteristics from Y.

Application in Shareholding Analysis

Graph transversal algorithms help in:

• Tracing how characteristics like consolidation methods and legal statuses are passed down in an MNE.
• Identifying and defining sub-trees, which simplifies the analysis of specific segments within the MNE.
• Assessing the hierarchical structure and its implications on corporate governance and compliance.

Conclusion

In the context of MNE shareholding structures, graph transversal algorithms are invaluable for dissecting complex networks. They aid in understanding the inheritance of critical characteristics and in defining distinct sub-trees within these multinational networks, providing clarity in corporate structure analysis.
