A* ALGORITHM BASICS FOR PATH FINDING A* , widely used known form of best-first search & path planning algorithm nowadays in mobile robots,games. this is the function for A*, f(n) = g(n) + h(n) g ( n ) is the cost of the path from the start node to n , and h ( n ) is a heuristic function that estimates the cost of the cheapest path from n to the goal This will find cheapest f(n) value in neighbor nodes to archive goal node. check below image A to B path finding with g(n),h(n),f(n) value In the final level check below image Now we will check the Algorithm // A* Search Algorithm 1. Initialize the open list 2. Initialize the closed list put the starting node on the open list (you can leave its f at zero) 3. while the open list is not empty a) find the node with the least f on the open list, call it "q" b) pop q off the open list c) generate q's 8 successors
ubuntu mate 18.04 remote RDP connection & ssh configuration fixed xrdp session: Login failed for display 0 in rasberry pi 3 B
This is for setup xrdp remote server sudo apt-get install xrdp This is for fixing Login failed for display 0 sudo adduser xrdp ssl-cert This is for enable ssh in rasberry pi and make it work to enable sudo raspi-config -> interfacing options -> ssh -> enable sudo rm /etc/ssh/ssh_host_* sudo dpkg-reconfigure openssh-server finally sudo reboot check this video
