Problem (Konigsberg Bridge Problem Updated): In Konigsberg, there are two additionalbridges, besides the seven that were present in the eighteenth century. These new bridges connectregions B and C and regions B and D, respectively.1. Check whether it is possible to start from one region, visit all regions, and return to thestarting point while visiting each region exactly once.2. Is it possible to cross all nine bridges in Konigsberg exactly once and return to thestarting point?Good Luck!

It is possible to visit each region once by not traversing all bridges. Starting point can be from…

The city of BeeOS has a sightseeing tour which departs from a bus stop, takes a city tour and arrives at the same bus stop. There is only one bus that takes these tours indefinitely. The city visitors wait at the bus stop to board the bus, which can hold maximum N people. Each visitor should queue up at the bus stop and not get on until the bus starts its engine. The bus should wait until N visitors have boarded before departing. The bus can start its tour only when it is full. Once the bus has finished the trip, the visitors should get off after the bus stops its engine. All visitors should leave before the bus starts again. The process codes to be run by the bus and visitors are given below without any synchronization. Note that ‘Visitor’ code will be called by each visitor separately.Bus{loop{start_engine();take_tour();stop_engine();}}Visitor{get_on();get_off();}Rewrite the Bus and Visitor codes, with convenient mutex and/or semaphore operations, such that all synchronization…
Intersections in England are often constructed as one-way "roundabouts," such as the one shown in the figure. Assume that traffic must travel in the directions shown. Find the general solution of the network flow. Find the smallest possible value for X8- X₁ = X3 X4 = X5 X is free X₁ = X₂ is free X₂ = X4 = X5 is free X8 is free 60 >>> Find the smallest possible value for xg. The smallest possible value for X is 100 B, *24 A X₁ 120 140 %3 What is the general solution of the network flow? Choose the correct answer below and fill in the answer boxes to complete your choice.

You are given the arrival and departure times of trains reaching to a particular station. You need to find minimum number of platforms required to accommodate the trains at any point of time. Trains arrival = [9:00, 9:40, 9:50, 11:00, 15:00, 18:00] Trains departure = [9:10, 12:00, 11:20, 11:30, 19:00, 20:00] The situation can be solved by using few algorithms. However, it will reflect the complexity of the solution. You are required to solve the problem using, (b) Greedy Algorithm i) Produce the complete algorithm ii) Calculate the minimum number of platforms based on algorithm in (b)(i) and show the process.
Mr. Cook is the manager of Code cinemas and after a long break the theatres are open to the public again. To compensate for the loss of revenue due to Covid-19, Mr. Chef wants to maximise profits from each show from now on, while following the guidelines set by the government. The instructions are: If two people are sitting in the same row, there must be at least one free seat between them. If two people are sitting in different rows, there must be at least one completely empty row between them. This means that if there are people sitting in rows i and j where i
I need the algorithm, proof of correctness and runtime analysis for the problem. No code necessary ONLY algorithm. And runtime should be O(n + m) as stated in the question.
