Tail Recursion vs Forward recursion in Erlang -

-

is tail recursion better forward recursion perfomance in erlang?
or erlang compiler optimizes forward recursion too?
mean, there reasons use tail recursion instead of forward recursion?
in opinion, forward recursion looks more pretty.

tail recursion better because uses less memory. bring need onto next call, minimizes memory utilization on stack. also, when tail recursive code optimized, function returns not needed thrown away make faster in cases.

for example, if function's return value call function, there no need keep intermediary function on stack. code jumps directly caller inner function.

non-tail recursion optimized tail recursion in cases erlang compiler, don't count on it. make habit code tail recursive functions whenever can.

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,
