Attention!
Do you want to be the best mathematician?Here's a new method to beat a sequential search that goes from 0 to N-1 !
It's called sequential-advanced, and it's based on solid mathematical and probabilistic theories. In fact, the probability that it does not find the key before the classic sequential method is 1/N that's 1/2^68 if we look at puzzle 69, almost zero!!
This means that, compared to the classic sequential search, the advanced method will find the key first in 99.99999999% of cases! Incredible.
But let's put it to the test with a script

TOTAL_SIZE = 10000
SIMULATIONS = 500
def generate_h160(data):
return hashlib.new('ripemd160', str(data).encode()).hexdigest()
def sequential(dataset, target_hash):
checks = 0
for i in range(len(dataset)):
checks += 1
if generate_h160(dataset[i]) == target_hash:
return {"checks": checks, "found": True}
return {"checks": checks, "found": False}
def sequential_advanced(dataset, target_hash):
checks = 0
for i in range(1, len(dataset)):
checks += 1
if generate_h160(dataset[i]) == target_hash:
return {"checks": checks, "found": True}
checks += 1 # check 0 at the end
if generate_h160(dataset[0]) == target_hash:
return {"checks": checks, "found": True}
return {"checks": checks, "found": False}

else:

print(f"Simulation {i+1}: Sequential = {res_seq['checks']} checks in {time_seq:.6f}s | Sequential-Advanced = {res_adv['checks']} checks in {time_adv:.6f}s")

Look at that! 500 to 0 unbelievable, right? Never use the normal sequential search again.
And dont use the prefix-method either, because against the original sequential approach, you might lose sometimes.
With this new method, instead, youre practically unbeatable!
But how does it work?
Simple: the advanced method searches sequentially starting from 1 instead of 0, and it checks 0 only at the end.
Checkmate to the sequential method from 0 to N-1!
I've found a method that retires it one that lets me find the key faster in 99.999999% of cases.
Right?
Puzzle 69 solved as soon as I posted 100% winrate method. Will accept donation too
