Progress reports

Prior to May 23:

Related to rSQP:

  • Started reading Mathematical and High-Level Overview of MOOCHO. However was later redirected to chapter 12 (Nonlinear programming) of "Operations Research: Applications and Algorithms" from Winston, 1994, 3rd (or a later) Ed., Duxbury Press (Belmont, California) as a preliminary reading for mathematical background.
  • Completed reading chapter 12 (Nonlinear programming) of "Operations Research: Applications and Algorithms".
  • Re-reading Mathematical and High-Level Overview of MOOCHO.
  • Revisited theory behind the Simplex Algorithm from "Introduction to Algorithms", 3rd Edition, Page 864-879 authored by Cormen, Leisersin, Rivest, Stein.

Related to Radau5:

  • Investigated code ascend/integrator/integrator.h and ascend/integrator/integrator.c to understand the data structures used.
  • Devised and tried implementation of various for the mass matrix problem in solvers/radau5/asc_radau5.c.
  • Settled on the idea of replacing neq with total number of equations as compared to the previous implementation of number of states.

  • Finding a temporary fix for the mass matrix problem. I have split the task as to finding solution to 2 problems:

(i) Making sure algebraic equations are being sent to solver.

(ii) Writing a feasible mass matrix function to generate the mass matrix. This depends on (i).

Regarding Solving Part (i), I made an outside link and was able to capture all the variables involved. Trying to use them to find total number of equations.
