snes | - SNES context |
version | - version 1 or 2 (default is 2) |
rtol_0 | - initial relative tolerance (0 <= rtol_0 < 1) |
rtol_max | - maximum relative tolerance (0 <= rtol_max < 1) |
alpha | - power for version 2 rtol computation (1 < alpha <= 2) |
alpha2 | - power for safeguard |
gamma2 | - multiplicative factor for version 2 rtol computation (0 <= gamma2 <= 1) |
threshold | - threshold for imposing safeguard (0 < threshold < 1) |
