Welcome to the FLINT wiki!

Things to do

• Choice of fixed-step size if user does not want adaptive step-size
• Check support for discontinuous events like a step function
• EventAction: Ability to modify solution from the user-provided event functions
• EventAction: Ability to restart integration after encountering a discontinuity in the differential equations and aility to cross the discontinuity before restarting
• Ability to mask events after first trigger
• Ability to detect events beyond which the first-order derivatives cannot be conveniently evaluated
• Ability to specify event step size and root-finding option for each event separately
• Option to set event root-finding tolerance for each event separately
• Option to return a refined bracket for event for use in integration through discontinuity, event state at the beginning or end of the step
• Test examples from https://reference.wolfram.com/language/tutorial/NDSolveWhenEvents.html
• Choice of different step-error and step-size computation formulae
• Compare the performance of matmul, gemm, and do loops for computation of ERK stages
• Implement hand-optimized step-integration routines for Verner98R/Verner65E also.

New Features

• Implement one General Linear Method (GLM) algorithm for stiff and non-stiff systems
• Adjoint method for computing parameter sensitivity matrices cheaply
