Plot the probability density function
$\qquad w(x)=(1/(1+x^2))(1/x^{0.5})$ for $(0 < x < 1)$
Make up the subroutine flowchart to get the random numbers $x$, using the modified rejection technique with first factor used as the comparison function.
Use the flowchart to get a few random numbers in Wolfram Mathematica
Trial answer:
a = 0; b = 1;
f[x_] := (1/(1 + x^2)) (1/x^0.5)
h = 1; Nt = 1000000;
gr1 = Plot[f[x], {x, a, b}]
S := (
x = y = b h;
While[y > f[x],
x = a + (b - a) RandomReal[];
y = h RandomReal[]];
Return[x];
)
rez = Table[S, {i, Nt}];
gr2 = Histogram[rez, Automatic, "PDF"]
Show[gr1, gr2]
w(x)
integrates to 1 over the interval (0,1). Do you meanSqrt[2]/pi w(x)
integrated from zero to infinity? $\endgroup$
