ODE initial value problem - Multistep methods - Predefined cases

Select the test problem please:

	f(y,t) = -2y with y(0) = 1 (description)
	f(y,t) = y2 with y(0) = 0.5 (description)
	the restricted three body problem(description)
	a nonlinear RLC circuit with a tunnel diode in parallel (description)
	the reduced Reynolds equation (description)
	f(y,t) = y2, if 0<= t <= 1/sqrt(2) and f(y,t) = 2(y-y(1/sqrt(2))-1), if t > 1/sqrt(2). initial value y(0) = 1 (description)

Select the integrator:

	Adams-Moulton P(EC)m
	BDF

Please specify: precision wanted
tol = Important: this is relative precision, 0 < tol < 1 !
The absolute error bound is tol × smally :
smally = Important: smally > 0 !

Specify the maximum stepsize allowed:
hmax=
Important: hmax > 0 . Too large hmax will be reset automatically .

Please specify the maximal order allowed:
maxorder=
Important: maxorder <= 12 for AM and <= 5 for BDF.

How many subintervals should be treated separately?
1 means direct integration from t₀ to t_end. 1 <= num <= 100.
