Hello! I like to experiment with genetic algorithms, open-ended systems, and physics-based simulations to explore emergent behaviors. I especially like the uncommon solutions evolution gives us! My research focuses on how simple interactions give rise to complex, self-organizing structures that may lead to adaptive, specialized and cooperative behaviors in different environments! Kinda like various cells coming together to make a multicelular organism! Currently, I'm experimenting with physics-based simulations to study how self-organization, adaptation, and collaboration emerge from simple rules! Check my bluesky/mastodon! I'm often posting videos of experiments!

Also, check my blog! :)

Projects [top]

  • EvoExperiment (2024)
    Done with python, using pygame for visualization. I wanted to integrate markov chains to a GA. Plants in this environment can stay idle, eat or reproduce. Transition matrix determine how the state transition happens. These matrixes may mutate by changing the transition probabilities. Different levels of energy were considered to different state levels. Looking forward to add more interaction between plants.

  • EvoPlants - PROCJAM2024 (2024)
    -- You can play here
    Done with python and pygame for visualization. Entry to procjam 2024. Each pixel may be occupied by a plant that has and RGB code as a gene. The color of each pixel is the average of the gene of its neighbors. Plants may either die, mutate or multiply themselves to its neighbors, each action determinated by chance. Changing mutation rates or including crossover between genes creates different color patterns on the screen. I intent to add more possible combinations. The web version needs to be updated.

  • Bloop!Jump - LOWRESJAM2023 (2023)
    -- You can play here
    Done with pico8. Entry to lowresjam 2023. A (difficult) platformer where a blob's goal is to get to the top of the stage. The blob can move left and right, its jump can be charged and if it hits a wall mid-jump, its trajectory can't be changed.

  • Rhymming and Saying (2023)
    Done with Python. A formal grammar that uses wordnet to look for words that rhyme with selected sayings. Words of specifics classes (adjective, adverbs, etc) have their last phoneme compared to the last phoneme of the saying to ensure they rhyme. Sometimes we get funny outputs.

  • RPG NPC file creator (2023)
    Done with Python. Used genetic algorithm to create character files for a TTRPG that I played with friends. A file was received as an input together with the desired % of wins. A population of files is generated and then goes through evaluation, recombination, mutation and selection until a certain threshold. It was a cool way to get enemies balanced with the DungeonMaster's intention. (Or a way for me to test my character files)

  • Arduino Robot (2017)
    Built with classmates during undergraduation. A wheeled robot that used ARDUINO-UNO to proccess signals from ultra-sound, clapper, magnetomer sensors and an app that could control the robot. The first three were used when the robot was on autonomous mode, and the last and an user was controlling it.
