List of potential user mistakes (continuously updated)

[jowaibel]

(umno User mistake No.) (Place in code) (Description)

---

umno1 OptProblem::add_variables User adds the same variable twice, e.g.,

for (int i = 0; i < N + 1; i++)
 {
    optProblem.add_variable(X_sym[i]); // TODO eno1: Loop through array in add_variable()
    optProblem.add_variable(X_sym[i]);
 }

--> Leads to segmentation fault at runtime.

---

umno4 User forgets to register a variable.
--> Segmentation fault at runtime. Debug mode tracks it down to the line where the unregistered variable appears.

---

umno5 User directly uses decision variables (i.e., variable_t members of Transcription) in (tagged) functors by accident.
--> Type mismatch when evaluating ControlProblem function implementations.

---

umno6 User writes to laopt::variable_t before the solver has been constructed.
--> Segmentation fault at runtime. Variables do not have a memory yet.
