I need to write a brute-force algorithm to count the number of unit triangles in a complex shape. The shape is created each iteration by adding triangles to surround all outer edges. The shape in iteration number n would look as above and the outputs would be 1 4 10 respectively.

Dec 28, 2024 · # Python code to count the number of possible triangles # using Two Pointers Technique def countTriangles (arr): res = 0 arr. sort # Iterate through the array, fixing the largest side at arr[i] for i in range (2, len (arr)): # Initialize pointers for the two smaller sides left, right = 0, i-1 while left < right: if arr [left] + arr [right ...

Aug 12, 2019 · Solution 1: use binary search to get O(n^2 log(n)) Pseudo code: for b in B: use binary search to find the highest index c_low in C_s s.t. C_s[c_low] <= |a-b|. use binary search to find lowest index c_high in C_s s.t. C_s[c_high] >= a+b. count += (c_high-c_low-1) Explanation and demonstration of correctness:

One day at work with Humanyze, I came across a particularly elegant and mysterious method to count the number of triangles in a node graph (in python). Suppose S is a numpy array of the square matrix representation of an undirected node graph (with no self edges), then.

def count_triangle(graph): n = 0: for wedge in wedge_iterator(graph): if graph.has_edge(wedge[1][0], wedge[1][1]) or graph.has_edge(wedge[1][1], wedge[1][0]): n += …
