HW3 is graded | |
|
Hi guys, HW 3 is graded. In general, all the submissions were great and I hope you enjoyed the exercise. There was one common issue among several groups which caused the deduction of 6 points and that was the choice of params. While I did not mention this explicitly, at this point along the course I expect you to choose parameters in an informative way. For example, groups that included a weight of 1.4 and 1.5 show good understanding because \sqrt{2}~ 1.41 is a "transition param" causes things to behave differently. A group that did not use Vanilla A* (i.e., w1 =1 ) or that chose w2 < 1 demonstrated that little thought was put into the set of params used to evaluate the algorithms. Oren |

HW2 Graded | |
|
Hi all, HW2 is graded. In general - great job! I hope you got some hands-on experience and intuition regarding how the different parameters affect the planners we learned. Some of the points that were deduced were because you did not provide what was asked of you - please make sure to read and follow the instructions carefully. Common things that caused points to be deduced: -3: Only one RRT version of RRT was used to plot the solution quality as a function of time and / or the the success rate as a function of time. -5: Sec 3.4, part (3) missing plots for RRT behavior -3: Sec 2, instead of eta_d(\eps) as a function of d for different values of \eps plotting eta_d(\eps) as a function of \eps for different values of d -3: visualizing only solution and not expanded states for A* or RRT tree for RRT / RRT* If you did not receive your HW back, either no points were deduced or one (or more) of the above were the only reasons points were taken off.

HW1 graded | |
|
Hi all, HW1 is corrected and grades published. In general, nice work! There were multiple submissions that confused between a line and a segment which resulted in a wrong answer. One point was deduced for this case. For other mistakes, I returned the pdf with an explanation of why points were taken off. If you wish to discuss the HW - feel free to reach out. Oren |

Size of an arrangement of lines | |
|
In last lecture we talked about the size of an arrangement of lines. There were several mistakes in the slide and I appologize. (1) The way we computed the number of vertices accounted for each vertex twice. We should have V = n(n-1)/2 and *not* V = n(n-1) (2) We can't use Euler's formula because we don't really have the bounding box (if you want to use it you should account for the additional edges / vertices) The real value is F = n^2/2 + n/2 + 1 The way to show this is by adding the lines one-by-one: Start with no lines and you have one face. When we add line number i we (*) add i additional edges (*) every edge splits a face in two Thus, we get 1 + sum_{i=1..n}(i) = 1 + n/2 + n^2/2 |

HW1 - correction1 | |
|
In the HW it states "square-shaped robot rotated by 90 degrees" Obviously this does not change the robot's geometry... What I meant was "an axis-aligned square-shaped robot rotated by 45 degrees" Best, Oren |

Technical instructions for class lectures | |
|
We are starting a challenging semester and I hope that together we will be able to learn and even enjoy our time together. Below are a few technical details for how to conduct our online lectures: (1) Please open your cameras when joining the class - online learning creates barriers to the personal interactions possible in class which in turn, can compromise the teaching quality. Turning cameras off reduces the possible interaction even more. (2) At the beginning of class you will be muted, feel free to unmute yourself to participate in a discussion or answer questions. Please mute yourself when you are done talking so we won't hear background noises. (3) I will not be able to look at the chat - feel free to use it to communicate between yourself but do not abuse it. (4) There is a link to the zoom meeting under "course material". Good luck to all of us, Oren |
