WebMar 30, 2024 · A greedy algorithm is an algorithmic paradigm that follows the problem-solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. In other words, a greedy algorithm chooses the best possible option at each step, without considering the consequences of that choice on future steps. WebMy algorithm is as follows: Simplified: For each 16x16x16 chunk, for each face (+x, -x, +y, -y, +z, -z), for each layer (16 per face), extract the visible blocks of the layer into a 2D array, then perform 2D meshing on the extracted layer.

WebA greedy algorithm is used to construct a Huffman tree during Huffman coding where it finds an optimal solution. In decision tree learning, greedy algorithms are commonly used, however they are not guaranteed to find the optimal solution. One popular such algorithm is the ID3 algorithm for decision tree construction. WebLike I said, I made a new greedy meshing algorithm.
