Enforce minimum spacing between non-zero elements in array

like below fixes the issue Here is a reasonably efficient way. It works by (1) first ignoring the minimum wait. (2) computing inter-event-times (3) adding the minimum wait,(4) going back to absolute times discarding events that have been shifted out the right end. It can create 10**7 samples in less than a second.
code :
import numpy as np

def train(T, dt, rate, min_wait):
    p = dt*rate
    # correct for minimum wait
    if p:
        p = 1 / (1 / p - min_wait) 
    if p > 0.1:
        print("warning: probability too high for approximation to be good")
    n = int(np.ceil(T/dt))
    raw_times, = np.where(np.random.random(n) < p)
    raw_times[1:] += min_wait - raw_times[:-1]
    good_times = raw_times.cumsum()
    cut = good_times.searchsorted(n)
    result = np.zeros(n, int)
    result[good_times[:cut]] = 1
    return result

Is it possible for Git to enforce spacing conventions on the server-side?

will help you Based on the comments and additional research, it appears Git's collaboration model makes it very difficult to force things on the server side.
My final solution was to use the filter I had and distribute a simple script for users to run to add the relevant configs to their system (as per the answer to Can I specify .git/config values in a repo).

how to enforce some spacing between the elements of 'addCategoryAxis'

this will help Ok, so- on the advice of @thisOneGuy I started playing around with increasing the width, and it worked.
At first I tried to increase the width too much and the chart just disappeared (if anyone knows why that happened I would be interested to hear about it in the comments perhaps)

will help you Here is a one-pass solution that
1) calculates the differences d between consecutive points
code :
def fill(data, step, force_power_of_two=True):
    d = data.copy()
    d[1:] -= data[:-1]
    if force_power_of_two:
        m = 1 << (np.frexp(np.nextafter(d / step, -1))[1]).clip(0, None)
    else:
        m = -(d // -step).astype(int)
    m[0] = 1
    d /= m
    return np.cumsum(d.repeat(m))
>>> inp
array([10.08 , 14.23 , 19.47 , 21.855, 24.34 , 25.02 ])
>>> fill(inp, 3)
array([10.08 , 12.155, 14.23 , 16.85 , 19.47 , 21.855, 24.34 , 25.02 ])

seems to work fine The issue your current code has isn't with large numbers, but with index 3. You never exclude that index from your calculations, so if it is the largest of smallest in your list, you'll get the wrong results.
The reason you never skip index 3 is that your outer loop runs is on range(0, 4), and the inner loop is too. That means you take four items, starting at indexes 0 through 3. But you never start at index 4, which is the situation where index 3 would be skipped.
code :
 for i in range(0, 5):            # replace 4 with 5 here!
    sum1=0
    for j in range(0,4):
        ...
def miniMaxSum(arr):
    arr_sum = sum(arr)
    min_val = min(arr)
    max_val = max(arr)
    print("Minimum:", arr_sum - max_val, "Maximum:", arr_sum - min_val)

like below fixes the issue Below is a Java Dynamic Programming algorithm.
(the C++ version should look very similar)
