Using the below image represent this family using a graph structure. The graph needs to be a weighted graph. The weights will constitute the types of relationships. It is recommended to use some kind of mapping between numbers and strings to represent the relationships. When adding family members to the graph, this can be done programmatically for the provided family members within the description file. Additionally, there should be an interface in which a user can create a new family member and add them to the tree.

This can be a simple CLI where the user provides a name, gender, and age to create a person. Then another simple CLI where they select which member of the family they want the original relationship to be with and what kind of relationship it should be. Lastly, they can edit the family member using another CLI and selecting the family member they wish to edit, the operation they wish to perform (edit name, edit age, edit relationship), and then add new relationships between family members, which can call a function created to add the original relationship. Finally, data assertions should be made within the FamilyTree class that enforce certain "rules" found in a typical human family.

An example would be a person should not have any kind of relationship to itself (a person cannot marry themselves, a person cannot be their own brother, sister, father, mother, etc.). There should be at least three data assertions. These should exist as part of the family tree, not as part of the graph. It is recommended to use layers of abstraction for successful design. The graph class serves as the backing structure to the family tree class.

The family tree should implement methods that interface with the graph class. For example, add_family_member() should call the constructor to create a node and then call a function within the graph class to add a node to the graph. Using the relationships function parameter, edges can be added to the graph between the new nodes and the existing nodes. The family tree should enforce what relationships can exist through data assertions; the graph itself does not care about the relationships made between family members. The function calls that the user would interface with would be limited compared to the total number of methods within the classes themselves. The user should be able to add, remove, and modify family members, and that should be the extent of the functionality provided.

Paper For Above Instructions

To effectively represent a family using a graph structure, we must first define the necessary components of our family tree as an object-oriented program. This involves creating two main classes: Graph and FamilyTree. The Graph class will serve as the underlying structure to hold family member nodes and their relationships, while the FamilyTree class will provide methods for interacting with the graph and enforcing the rules of family relationships.

Graph Structure

The Graph class will be implemented to create a weighted graph. Each node in the graph represents a family member, and the edges denote relationships between members, which will be weighted to represent the type of relationship. For example, we could assign the following weights:

  • 1: Parent
  • 2: Sibling
  • 3: Spouse
  • 4: Child

These mappings can be defined in the constructor of the graph. The graph will contain methods to add nodes (members) and edges (relationships), which will be linked to the family tree.

Family Tree Class

The FamilyTree class will use the Graph class to implement methods such as add_family_member(), which will add a new member to the graph and establish relationships based on user input.

To enforce the rules of familial relationships, data assertions will be included. Three critical assertions could be:

  • A member cannot have a relationship with themselves.
  • A child cannot be a parent of their parent.
  • A sibling cannot have a spouse relationship with their sibling.

These assertions must be checked whenever a new relationship is added. If any of the assertions fail, an error should be raised, preventing inconsistencies in the family tree.

User Interface

For user interaction, we can create a Command-Line Interface (CLI) with options to add, remove, and edit family members. A simple menu could be used to guide users through the process of entering data:

1. Add Family Member


2. Edit Family Member


3. Remove Family Member


4. Exit

When adding a family member, users will input information such as name, gender, and age. Upon adding, they will be prompted to define relationships with existing members.

For editing family members, users can select the member they wish to edit and the type of operation (edit name, age, or relationship). The system will ask for necessary details and apply them accordingly. Finally, removing a family member will involve identifying the member and confirming the removal.

Program Implementation

The overall program design thus leverages the strength of object-oriented programming. The FamilyTree class holds the management of members and relationships while the Graph supports the underlying data structure with enhanced capabilities for connecting family members. This dual-layer structure leads to easier maintenance and scalability of the family tree.

The family tree can thus extend as necessary with potential for dynamic relationships based on user input, promoting an interactive experience in creating family graphs.

Conclusion

In conclusion, this document outlines the architecture and requirements of developing a family tree represented as a weighted graph. The obligations detailed encourage a robust, maintainable, and user-friendly interface for managing family relationships, in accordance with critical familial rules and interactions. This program could serve as a foundation for more advanced genealogical tools and applications.
