Comparing two small networks using dense layers. According to Keras' documentation both should be identical
from keras.models import Sequential
from keras.layers import Dense, Flatten
model1 = Sequential()
model1.add(Dense(1, input_shape=(10,10)))
model2 = Sequential()
model2.add(Flatten(input_shape=(10,10)))
model2.add(Dense(1))

A small parser with some visualization for go .sgf replays
import numpy as np
import sgf # pip install sgf -- simple parser for the file format
def decode_position(pos_string):
# position in .sgf is char[2] and row-first, e.g. "fd"
positions = "abcdefghijklmnopqrs"
x = positions.index(pos_string[0])
y = positions.index(pos_string[1])
return y, x

This is the full version of the code for my answer at https://codereview.stackexchange.com/questions/191218/go-board-game-check-for-removed-stones
import numpy as np
import sgf # pip install sgf -- simple parser for the file format
import timeit
def decode_position(pos_string):
# position in .sgf is char[2] and row-first, e.g. "fd"
positions = "abcdefghijklmnopqrs"
x = positions.index(pos_string[0])
y = positions.index(pos_string[1])
return y, x

Solution for the first question of the Google Code Jam 2018. (It passes the first round of tests, but is to slow for the second; thus requires runtime optimization. Can you see what could be changed? :) )
from collections import deque
import sys
def get_damage(sequence):
current_strength = 1
damage = 0
for char in sequence:
if char == "C":
current_strength *= 2

My answer to the second problem of the Code Jam. It has a small error: Instead of printing "Case #1:" it's printing "Case 1:" ... small things :D
import sys
def trouble_sort(L):
# in place sorting
done = False
while not done:
done = True
for idx in range(len(L) - 2):
if L[idx] > L[idx + 2]:
done = False

The code from https://codereview.stackexchange.com/questions/192027/genetic-sequence-visualizer-generating-large-images slightly optimized. It avoids storing things that can easily be computed on the fly saving 40x memory.

Code from: https://codereview.stackexchange.com/questions/192027/genetic-sequence-visualizer-generating-large-images ; No longer uses `largearray` and removed timing statements (can be done better with cpython)
