Path Finding Visualization vs Ancient Language Learner

Want to see various pathfinding algorithms in action? With Path Finding Visualization, you can visualize, in action, six different algorithms. This app allows you to select your own starting and ending points, select the algorithm you want to use, and add walls in order to create boundaries. This app includes the following algorithms: Dijkstra's - Works by expanding outwards until it reaches the target node. Guaranteed to find the shortest path as long as there are not any negative weights. Bidirectional Dijkstra's - Dijkstra's algorithm from both sides. A* - Like Dijkstra's in that it favors nodes close to the starting point, but also favors nodes close to the ending point (heuristic). It does not guarantee the shortest path. A tie-breaker that prefers straight lines was included in order to prevent multiple nodes from having the same F values. Bidirectional A* - The A* algorithm from both sides. Breadth-First Search - Traverses through a graph one level at a time until it finds the target node. Since there are no weights, this algorithm does guarantee the shortest path. Depth-First Search - Traverses through a graph by going as deep as possible and then backtracking until it finds the target node. It does not guarantee the shortest path. Learning about or want to visualize any of the above algorithms in action? Download Path Finding Visualization today and have a better understanding of how each algorithm works.

Learn the vocabulary of the New Testament — all 5,483 words — through the screens you already look at dozens of times a day. HOW IT WORKS • New words appear on your lock screen with their meaning, several times through the day — no app to open. • The Recall widget on your home screen quizzes you: read the Greek, tap to check, then grade yourself. • Every PASS stretches the next review out (1, 3, 7, 14, 30, 90, 180 days). Every ↺ brings the word back sooner. Miss a word two days running and it returns to the lock screen for relearning. A REAL DICTIONARY BEHIND EVERY WORD Tap any word for its full entry: the Middle Liddell definition, the forms that actually occur in the New Testament with their parsing, its frequency across the Septuagint, the Apostolic Fathers and wider Greek literature — and every NT verse it appears in, with translation. MADE TO BE SUSTAINABLE • A two-minute placement test finds where you should start. • Choose which days introduce new words — take Saturdays off. • Reviews are capped and smoothed automatically, so the backlog can never snowball. • Words common in the Septuagint and the Fathers but rare in the NT are woven in, so your Greek grows beyond the canon. ALSO INCLUDED Hebrew and Latin vocabulary decks, and Hebrew verb-form drilling, available under Manage Languages. Built by a student of the biblical languages, on the conviction that the lock screen is the best flashcard you own.
