Graphs Help Really Challenging Assignment Would Appreciate Any

Family tree's and genealogy software has become more and more prevalent in recent years. From the name you might expect that a family tree would be easily represented by a tree structure, but that is not the case! A more appropriate data structure to represent a family tree would be a type of graph.

Using the description of the family that accompanies this assignment, you must represent this family using a graph structure. The graph needs to be a weighted graph. The weights will constitute the types of relationships, I recommend using some kind 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, I also want there to 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. Finally, 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 relationship between family members which can call a function that you create in order to add the original relationship. Remember the DRY philosophy, where code can be modularized or made into a function, it should be if you plan on using the logic again.

Finally, I want you to make data assertions within the FamilyTree class that enforce certain "rules" that exist in a typical human family. An example would be a person should not have any kind of relationship to itself (a person can not marry themselves, a person can not be their own brother, sister, father, mother, etc.). There should be at least 3 data assertions. These should exists as part of the family tree, not as part of the graph. As a hint, for a successful design: I would recommend using layers of abstraction.

Your graph class is the backing structure to the family tree class. Your family tree should implement methods that interface with the graph class, i.e. 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. Then using the relationships function parameter, you can add edges to the graph between the new nodes and the existing nodes. The family tree should be what enforces what relationships can exist through the data assertions, the graph does not care about what relationships are made between family members. Your functions that the user would interface with would be greatly reduced 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's about it. Therefore those should be your function calls.

Paper For Above Instructions

In recent years, the emergence of genealogy software and family tree representations has become increasingly relevant. While one might assume that a family tree would ideally fit a tree structure, complexities in familial relationships suggest that a graphical representation through a weighted graph is far more appropriate for accurately encapsulating familial ties. This paper aims to operationalize such a representation through a programming assignment that requires the development of a FamilyTree class, incorporating functionalities to model real-world family dynamics rigorously.

Understanding Graph Representation

A family tree can be effectively illustrated as a weighted graph in which nodes represent family members, and weighted edges encapsulate varying types of relationships among these members. The assignment stipulates the construction of a family tree using graph theory, elaborating on relationships such as marriage, siblings, and offspring. To visualize the connections, we can employ adjacency matrices and lists, enhancing our program’s structural integrity and performance (Kelley, 2019).

Implementation Strategy

To fulfill the assignment’s requirements, we will implement a class called FamilyTree, building upon a graph data structure, which will include various methods. These methods include:

  • add_family_member(name, gender, age)
  • remove_family_member(name)
  • edit_family_member(name, property, new_value)
  • add_relationship(member1, member2, relationship_type)
  • display_family_tree()

The class structure will enable modular and reusable code segments, following the DRY (Don’t Repeat Yourself) principle effectively. Each method will spur interaction with the underlying graph, establishing a hierarchy and enforcing rules about familial relationships.

Data Assertions and Relationship Rules

Data assertions will play a pivotal role in maintaining the consistency of the family tree. They will ensure that several core relationship rules are respected:

  • A person cannot have a relationship with themselves.
  • A parent cannot adopt their biological child.
  • Siblings cannot marry each other.

These data constraints enforce a semantic structure that mirrors societal norms surrounding familial relationships while ensuring data integrity within the FamilyTree class (Smith, 2020).

User Interface

The simplicity of the user interface is crucial for usability, facilitating family member creation and editing through a Command Line Interface (CLI). Users can input names, ages, and gender, establishing the foundational attributes of each family member. Furthermore, users will select existing family members for relationship additions and modifications. These logical flows will enhance interaction, making the system intuitive and user-friendly (Johnson, 2021).

Graph Data Structure Implementation

The graph will be implemented as a dictionary, where each family member is a key connected to a list of their relationships. This dictionary structure enables us to quickly reference all relationships a specific family member holds. An adjacency matrix can also be constructed to illustrate relationships visually, providing two complementary perspectives of family ties (Harari, 2018).

Example Implementation

class FamilyTree:


def __init__(self):


self.graph = {}


def add_family_member(self, name, gender, age):


if name not in self.graph:


self.graph[name] = {'gender': gender, 'age': age, 'relationships': {}}


else:


raise ValueError("Member already exists.")


def add_relationship(self, member1, member2, relationship_type):


if member1 == member2:


raise ValueError("A person cannot have a relationship to themselves.")


Additional logic will go here


Further methods and logic can be constructed accordingly

This example lays the groundwork for the FamilyTree class, hinting at deeper methods involving relationship checks and data assertions.

Conclusion

The construction of a family tree using a graph not only allows for a user-friendly experience but also mirrors the complexity and nuance of familial relationships. This programming assignment encourages engagement with foundational concepts of graph theory while employing them to solve real-world problems. Through rigorous assertions and engaging user interactions, a robust system can be architected to trace family histories effectively.
