Advent of Code 2022 in pure TensorFlow - Day 11

In this article, we'll show how to solve problem 11 from the Advent of Code 2022 (AoC 2022) using TensorFlow. We'll first introduce the problem and then provide a detailed explanation of our TensorFlow solution. The problem at hand revolves around the interactions of multiple monkeys inspecting items, making decisions based on their worry levels, and following a set of rules.

Advent of Code 2022 in pure TensorFlow - Day 10

Solving problem 10 of the AoC 2022 in pure TensorFlow is an interesting challenge. This problem involves simulating a clock signal with varying frequencies and tracking the state of a signal-strength variable. TensorFlow's ability to handle complex data manipulations, control structures, and its @tf.function decorator for efficient execution makes it a fitting choice for tackling this problem. By utilizing TensorFlow's features such as Dataset transformations, efficient filtering, and tensor operations, we can create a clean and efficient solution to this intriguing puzzle.

Advent of Code 2022 in pure TensorFlow - Day 9

In this article, we'll show two different solutions to the Advent of Code 2022 day 9 problem. Both of them are purely TensorFlow solutions. The first one, more traditional, just implement a solution algorithm using only TensorFlow's primitive operations - of course, due to some TensorFlow limitations this solution will contain some details worth reading (e.g. using a pairing function for being able to use n-dimensional tf.Tensor as keys for a mutable hashmap). The second one, instead, demonstrates how a different interpretation of the problem paves the way to completely different solutions. In particular, this solution is Keras based and uses a multi-layer convolutional model for modeling the rope movements.

Advent of Code 2022 in pure TensorFlow - Day 8

Solving problem 8 of the AoC 2022 in pure TensorFlow is straightforward. After all, this problem requires working on a bi-dimensional grid and evaluating conditions by rows or columns. TensorFlow is perfectly suited for this kind of task thanks to its native support for reduction operators (tf.reduce) which are the natural choice for solving problems of this type.
