Multiplicative change for nonzero parameters when constructing
the initial simplex, default is 0.05. If a starting point has
a nonzero value x for some dimension, then the value will be
perturbed to x * (1 + deltaNonZero)
Absolute change for zero parameters when constructing the
initial simplex, default is 0.001. If a starting point has a
zero value x for some dimension then this value will be
perturbed to deltaZero
Should we raise an error if the target function fails? If
true then any error in the target function is propagated out
from the solver, while if false then failure in the target
function is converted into a return value of -Infinity (this
is the default behaviour). The default behaviour is designed
for use for functions where some parameters may not make
sense, and can be used to implement bounded optimisation by
raising an error if the parameters are unsuitable.
Tolerance used in the convergence heuristics. Default is 1e-5. Setting this value too small is likely to result in issues with floating point arithmetic, or very slow convergence in the final steps.
