1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...

Problem 7.2 (Volterra principle). Show that for any orbit of the Volterra- Lotka system (7.3), the time average over one period 1 1 T | (0)2 = 1, T | g(t)dt =1 is independent of the orbit. (Hint: Integrate log(r(t)) over one period.) 7.1. Examples from ecology In this section we want to consider a model from ecology. It describes two...

5. Consider the nonlinear two dimensional Lotka-Volterra (predator-prey) system z'(t) = z(t)[2-2(t)-2y(t)l, y'(t) = y(t)12-y(t)--2(t)] (a) Find all critical points of this system, and at each determine whether or not the system is locally stable or unstable. (b) We proved in class, using the Bendixson-Dulac theorem, that this system has no periodic solution with trajectory in the first quadrant of the plane. Assuming this, use the Poincare-Bendixson theorem to prove that all trajectories (z(t),y(t)) of the system (2) with initial...
Consider a state space where the start state is number 1 and each state k has two successors
Question5: [9 points] Consider a state space where the start state is number 1 and each state k has two successors: numbers 2k and 2k+1.a. Draw the portion of the state space for states 1 to 15 .b. Suppose the goal state is 11 . List the order in which nodes will be visited for breadth first search, depth-limited search with limit 3 , and iterative deepening search.c. How well would bidirectional search work on this problem? What is the branching...

4. Matlab Solvers: A Case Study in Mechanics Suppose we have two objects orbiting in space, with masses 1 - and , rotating around each other. For example, think of the earth and the moon, where the moon moves around the earth at distance 1. (Of course, here both the masses and the distance are normalized.) A third object, which is relatively much smaller and does not affect the motion of the first two, is also orbiting in space. Think...
