I'm glad to inform you about new quarterly release 0.34 of the free
(even for commercial purposes, license: BSD) cross-platform OOSuite
package software (OpenOpt, FuncDesigner, SpaceFuncs,
* Python 3 compatibility
* Lots of improvements and speedup for interval calculations
* Now interalg can obtain all solutions of nonlinear equation
(example) or systems of them (example) in the involved box lb_i <= x_i
<= ub_i (bounds can be very large), possibly constrained (e.g. sin(x)
+ cos(y+x) > 0.5).
* Many other improvements and speedup for interalg.
