java - Balancing pebbles problem -

-

i have stumbled upon problem before, balancing problem. program takes in array of integers of size n. program determines if array of integers can split 2 equal parts, sums of integers in each half being equal.

ex. 1 2 3 8 10 4

in which, program returns true, meaning can split 2 halves 14 in each

i know concerned combinations/permutations , i'm not @ them. i've managed think of brute force method. can solved using other methods? more efficient algorithms maybe?

a step step solution helpful. thank much

this partition problem can readily seen equivalent subset sum problem , knapsack problem. np-complete, , thought can't appreciably better exhaustive listing of combinations.

you can check possible ways readily: each element, it's either in left half or right half.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
