CS 581: Algorithmic Genomic Biology
Homework policy:
Homework problems
from the textbook are based on homework problems at the end of
each chapter.
Homework must be submitted via MOODLE and are
due by 1 PM on the due date.
Most homework up to April 4 can be submitted up to
48 hours late for reduced credit; note that
some homeworks (and all due after April 4)
must be submitted on time for any credit.

HW 14:
Read, compare, and critique two or more papers about
any topic we've studied in this semester.
All papers

Extra credit.
Consider the following model of site evolution.
You have a rooted binary model tree T and substitution
probability p(e) on each edge e that must be
greater than zero and less than 1.
The state at the root is the number of leaves in the tree T.
If the site
changes on edge e, the new state is the number of leaves below
e.
For this model answer the following questions:
- Which parameters of the model are identifiable?
(In other words, is the unrooted tree topology identifiable?
What about the location of the root? What about the
substitution probabilities?)
- If you constrain the model so that
the substitution probabilities on different edges are different,
which parameters of the model are identifiable?
- For those parameters that are identifiable,
describe a polynomial time algorithm to estimate
the parameters and prove that it is consistent.
- April 14. Submit proposal for final project.
- April 19:
HW problems from chapter 11: do three of
2, 6, 7, 10
- April 26: No homework. Submit draft of final project for comments.
- May 3: No homework. Final project due.
