Example 1

Use the initial_population_02 function to generate a new population (five agents) considering the three dimensional combinatorial problem.

# Import
# pip install metapy-toolbox or pip install --upgrade metapy-toolbox
from metapy_toolbox import initial_population_02 # or import *

# Data
nPop = 5
d = 3

# Call function
population = initial_population_02(nPop, d)

# Output details
print('particle 0: ', population[0])
print('particle 1: ', population[1])
print('particle 2: ', population[2])
print('particle 3: ', population[3])
print('particle 4: ', population[4])

particle 0:  [1, 0, 2]
particle 1:  [2, 1, 0]
particle 2:  [2, 1, 0]
particle 3:  [2, 0, 1]
particle 4:  [2, 1, 0]
