cps765-complex_networks-projeto_final-similaridade_entre_alunos

This article uses a dataset of answers to questions to generate student similarity networks. Two similarity functions to determine the weights between each pair of students are used, one that assumes a power-law distribution of answers response times, and one that does not. The resulting networks are then clustered using different communi

eel816_human-engine_chess

A variant on top of "Hand & Brain" chess, using speech interface. A player vocalizes the type of a piece [Pawn,King,Queen,Bishop,Knight,Rook], the Engine (StockFish 11) will play on the board what they regard as the best move with such piece type. Then it's the other player's turn. Game logic on Assets/Python. https://docs.google.com/presentation/d/1YOBRfllSFd9a2kmSXaNBtiMBxVp-5ADj-kDxY774jM4/edit?usp=sharing

graphql-admin-schema-provider

Example of Schema for Generic Graph Database Manager (https://github.com/FilipePrates/graphql-admin) demo

happyset-ic

For an undirected graph G = (V, E) and a subset S ⊆ V of vertices, a vertex v is happy if v and all its neighbors are in S; otherwise unhappy. Given an undirected graph G = (V, E) and an integer k, the goal of MaxHS is to find a subset S ⊆V of k vertices such that the number of happy vertices is maximized.

intuitive-management-interface-for-graph-database

This repo describes an intuitive interface for management of graph data, allowing for easy navigation and arbitrary manipulation of the nodes and edges. As an example, it describes an implementation using a Neo4j database that is managed through a GraphQL API and a Vue.js web interface.
