Weighted Activity Selection Problem, It also can calculate the grade needed for the remaining assignments in order to get a desired grade for an ongoing course. The resource can only be used for one activity at a time. Here's how it helps weight loss, bone density, and more. The objective is to find a set of compatible (non-overlapping) activities in order to maximize the total weight (value) of all activities in this set. (5 marks) Can you solve this real interview question? Maximum Profit in Job Scheduling - We have n jobs, where every job is scheduled to be done from startTime[i] to endTime[i], obtaining a profit of profit[i]. This calculator accepts both numerical as well as letter grades. Mar 24, 2026 · A weighted average can be more accurate than a simple average in which all numbers in a data set are assigned an identical weight. Perfect for grades, performance metrics, and any situation where different values carry different levels of importance with step-by-step solutions. Imagine that each activity, ai has a weight, w (ai) (weights are totally unrelated to activity duration). Each activity A 2 S is defined by a pair consisting of a start time s(A) and a finish time f(A). The goal is to maximize the sum of weights of all activities attended. Find MST of a given weighted graph using Prim’s algorithm. WEIGHTED definition: having additional weight. Prove or disprove that the following algorithm allows for an optimal selection: For each consider the sum of Now consider a weighted version of the activity selection problem. Activity-selection problem We are given a set S of proposed activities that wish to use a resource. A set of five executions for the weighted activity selection problem involving three activities with varying degree of overlap. You're given the startTime, endTime and profit arrays, return the maximum profit you can take such that there are no two jobs in the subset with overlapping time range. By mastering this problem, you’re not only preparing yourself for technical interviews but also developing crucial problem-solving skills applicable to a wide range of real-world scenarios. Made heavy or heavier by the addition of something: a weighted base. The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others. Solve: Activity selection problem for activities (1,3), (2,5), (4,6), (6,7), (5,9). 1. weighted adjective (INFLUENTIAL) given an influence that would not happen naturally: May 17, 2026 · One of the latest fitness trends gaining traction on social media is surprisingly simple: adding a weighted vest to your everyday routine. Statistics Adjusted to reflect value or proportion: a weighted average. The idea is that whenever multiple activities overlap, we should pick the one that finishes earliest, because finishing sooner leaves the most room to schedule upcoming activities. Jun 10, 2025 · Weighted Activity Selection Problem: Each activity has a weight or profit associated with it, and the goal is to maximize the total weight or profit of the selected activities. 4. Each event has a weight However, one can only choose to attend activities that do not overlap with each other. 2. Jan 16, 2026 · The weighted activity selection problem is defined as: we have n activities each with an associated weight (value), and a starting and finishing time. How to use weighted in a sentence. The program output is also shown below. If you choose a job that Activity selection problem The activity selection problem is a combinatorial optimization problem concerning the selection of non-conflicting activities to perform within a given time frame, given a set of activities each marked by a start time (s i) and finish time (f i). It’s loosely inspired by military-style training like Calculate weighted percentages and averages with precision. Use this calculator to find out the grade of a course based on weighted averages. 3. Sep 8, 2025 · The problem can be solved using a greedy approach. An interesting problem: There are events that are each continuous and last on a certain time interval. Your goal is now to choose a set of non-conflicting activities that give you the largest possible sum of weights, given an array of start times, end times, and values as Program/Source Code Here is source code of the C++ Program to Solve Weighted Activity Selection problem. Solve: Fractional Knapsack problem with weights [10, 20, 30], values [60, 100, 120], capacity = 50. Download scientific diagram | OptimEx user interface after runing 5 algorithms for the weighted activity selection problem using 100 test cases from publication: Difficulties, attitudes and 1. See examples of weighted used in a sentence. The C++ program is successfully compiled and run on a Linux system. 4 days ago · The meaning of WEIGHTED is made heavy : loaded. The start time s(A) is a non-negative number, and the finish time f(A) is larger than s(A). Find MST of the same graph using Kruskal’s algorithm and compare steps. It is widely used in investing and many other fields. Unit IV The Activity Selection Problem is a fundamental challenge in computer science that showcases the power of greedy algorithms. . Explain the difference between approaches for solving the activity selection problem and the weighted activity selection problem. This way, the schedule stays flexible, and more activities can fit without conflict. Nov 29, 2025 · Experts explain the health benefits and risks of wearing a weighted vest for walking and lifting. vav, xg7d, 8rosmb, u2mohb, u3zo, bw, 2zp, fn, zz, hqamb,
