Anytime algorithms in Python

Project description

INSTALLATION:

sudo -H pip3 install anytime

USAGE EXAMPLE:

"""

The following example program gets a very large vector

and tries to find the largest element in the vector.

It stops after a pre-specified time, and returns the largest element found so far.

"""



import random, numpy as np

from AnytimeAlgorithm2 import AnytimeAlgorithm



class MaximumFinder(AnytimeAlgorithm):

    def __init__(self, vector):

        self.vector = vector

        self.currentMaximum = 0



    def update(self):

        i = random.randint(0,len(self.vector)-1)

        if self.vector[i]>self.currentMaximum:

            self.currentMaximum = self.vector[i]

            print("self",self,"result",self.currentMaximum)



    def result(self):

        return self.currentMaximum



v = np.random.rand(10000000)

finder = MaximumFinder(v)

print(finder.result_after(0.0001))  # seconds

print(finder.result_after(0.001))  # seconds

print(finder.result_after(0.01)) # seconds
