Using a for loop to make a cartopy plot of lines from different latitude and longitude coordinates from a csv file

Asked 2022-Apr-17 at 22:56

The goal for my code is to make a rough roadmap using the latitude and longitude of the exits on the pennsylvania turnpike drawing a line between each exit.

I am using a for loop to plot a line on the map every time it loops. This works if i hard code the latitude and longitude but as soon as i plug in my variables nothing gets plotted. Since the coordinates are in order I am just increasing the index every time it loops to get the next coordinates. I have printed the variables inside the loop and verified they have the desired value. I have tried putting the values in ordered pairs but the plot function didn't like me using nparrays. I'm not sure if there is something simple i am missing, but I appreciate any input.

Okay, based on the discussion above, see below for a solution.

Notes:

Am using pandas DataFames to easily work with the .csv file. the names field is the column names.
Am not using orthographic projection at all.
Am iterating through the list of highway exits one exit at a time; at each index, am extracting the current and next exits' data - am sure there's a more 'pythonic' way to do this, but this is readable at least.
edit: the final index in the loop is length-1

Using st_sample works, but wasn't totally straightforward. The size of the road data makes it hard to work with in-memory.

Below the road_canada object is simplified, uses only the geometry column, combined, sampled, and finally had to be cast to POINT to get the coordinates to show up.

QUESTION

Showing that Greedy algorithm exhibits optimal substructure and greedy choice

Asked 2022-Mar-21 at 07:01

I am in need of help proving that an algorithm has greedy choice property and optimal substructure.

Context of the problem:

Consider a problem where a company owns n gas stations that are connected by a highway. Each gas station has a limited supply g_i of gas-cans. Since the company don't know which gas station is most visited they want all of them to have the same amount of gas.

So they hire a fueling-truck to haul gas between the stations in their truck. However, truck also consumes 1 gas-can per kilometer driven.

Your task will be to help the chain calculate the largest amount of gas-cans g_bar they can have at all Stations.

Consider the example: Here we have g = (20, 40, 80, 10, 20) and p = (0, 5, 13, 33, 36) (in kilometers). In order to send one gas-can from station 3 to station 4 we need to put 41 gas-cans in the truck, as the fueling-truck will consume 40 before reaching their destination (to send two gas-cans we need to put 42 in the truck). The optimal g_bar for the example is 21 and can be achieved as follows:

Station 2 sends 11 gas-cans towards Station 1. One gas-can arrives while ten are consumed on the way.
Station 3 sends 59 gas-cans towards Station 4. 19 arrive while 40 are consumed on the way.
Station 4 now has 29 gas-cans and send eight towards Station 5. Two of these arrive and six are consumed on the way.
The final distribution of gas-cans is: (21, 29, 21, 21, 22).

Given an integer g_bar. Determine whether it is possible to get at least g_bar gas-cans in every Gas Station.

in order for the greedy choice property and optimal substructure to make sense for a decision problem, you can define an optimal solution to be a solution with at least g_bar gas-cans in every gas station if such a solution exists; otherwise, any solution is an optimal solution.

Input: The position p_i and gas-can supply g_i of each bar. Here g_i is the supply for the bar at position p_i. You may assume that the positions are in sorted order – i.e. p_1 < p_2 < . . . < p_n.

Output: The largest amount g_bar, such that each gas-station can have a gas-can supply of at least g_bar after the truck have transferred gas-cans between the stations.

How can i prove Greedy Choice and Optimal Substructure for this?

...

ANSWER

Answered 2022-Mar-20 at 06:03

Let's define an optimal solution: Each station has at least X gas cans in each station (X = g_bar).

Proving greedy property

Let us assume our solution is sub-optimal. There must exist a station i such that gas[i] < X. Based on our algorithm, we borrow X - gas[i] from station i+1 (which is a valid move, since we had already found a solution). Now station i has gas = X. This contradicts the original assumption that there must exist a station i such that gas[i] < X, which means our solution isn't suboptimal. Hence, we prove the optimality.

Proving optimal substructure

Assume we have a subset of the stations of size N', and our solution is suboptimal. Again, if the solution is suboptimal, there must exist a station i such that gas[i] < X. You can use the greedy proof again to prove that our solution isn't suboptimal. Since we have optimal solution for each arbitrary subset, we prove that we have optimal substructure.

OpenCV BackgroundSubtractor Thinks A Busy Foreground Is The Background

Asked 2022-Jan-31 at 14:14

I am using background subtraction to identify and control items on a conveyor belt. The work is very similar to the typical tracking cars on a highway example. I start out with an empty conveyor belt so the computer knows the background in the beginning. But after the conveyor has been full of packages for a while the computer starts to think that the packages are the background. This requires me to restart the program from time to time. Does anyone have a workaround for this? Since the conveyor belt is black I am wondering if it maybe makes sense to toss in a few blank frames from time to time or if perhaps there is some other solution. Much Thanks

ANSWER

Answered 2022-Jan-31 at 14:14

You say you're giving the background subtractor some pure background initially.

When you're done with that and in the "running" phase, call apply() specifically with learningRate = 0. That ensures the model won't be updated.

Install Highway

HighwayJs is designed to be incredibly simple! Just follow a few simple steps to get started!. You need to add HighwayJS to your project. This can be done either by downloading highway.js or highway.min.js from the src folder in this repository, or by using bower - bower install highway. Create a basic html page and load the highway.js script. You should also have a <div> that has an attribute called highway-view. This will be where each page will be displayed. Create any HTML files required for each of your pages or add a script tage to your page that contains the html. The script tag should have the type 'text/html' and an id which you state as the template in the routes config. Create a javascript file to set up the routes. Use highway.configureRoutes to set up the routes. It should receive an object with a routes property which will be an array of route objects, and a property called default which will define the state to go to when one was not specified. A route object must have a state property. This is a string that is essentially the name of the page. This will be displayed in the url. You also need a template property which is the reference to the HTML file for that view. An additional viewmodel property may be defined that allows a you to set up and tear down a view once it has been displayed. The view model should have an init function which should accept one argument which will contain the root element contained in the template. Another function called destroy can be defined that will be called once a page is left. This allows you to cleanup anything specific to the view. To navigate between views simply use an a tag and set the href to #state.
