Secondly, a power driven vessel of less than 7 metres in length and capable of a maximum speed that is less than 7 knots, is allowed to display a single all round white light in lieu of everything else. These then become a single all round white light. Trials can be run in batch to analyze performance and accuracy of different Solver algorithms. The app allows for Solver implementations in various languages which all pipe into the same analyzer. There are a couple of exceptions to the above light configuration for power driven vessels.įirstly, a vessel of less than 12 metres in length is allowed to combine the masthead light and stern light. There are likely more manufacturer variants of the Minesweeper Badge than of any other Kriegsmarine service badge. MineSweeper Solution Analyzer is a native desktop application for analyzing and visualizing programmatic solutions to the game MineSweeper. This is important as under the IRPCS (or ColRegs) this makes us the overtaking vessel and therefore the ‘Give Way’ vessel. Actually, it's just a combination of two 12 patterns: Apply the 12 pattern from the left. M 121 The 1 2 1 pattern has one solution. We therefore know we are approaching the vessel stern. If the purple cells can't both be mines, then there must be three mines in the three remaining cells. When this light is visible to us, we can’t see any of the bow or steaming lights.
Most smaller vessels don’t have the structure to accommodate this.įinally, a power driven vessel has a single white stern light. However, this is usually impractical because the rules state that the second masthead light must be 4.5 metres higher than the first. The reason we state that two mast head lights ‘probably’ mean over 50 metres is because smaller vessels are also allowed two masthead lights. DISTRESS SIGNALS – from the IRPCS and Colregs.

How To Use Tidal Curves – watch the video.Powerboat Training Courses – a useful guide.This is an extension of the 1-2 pattern, in that two of the pattern exist side-by-side. The 1-2-1 pattern One of the frequently-encountered patterns along walls in Minesweeper is the 1-2-1 pattern. How Do Lifejackets Work? And How to Wear Them Note that in the second case, since there is a mine next to the 3 and 2, they need 2 and 1 mines respectively, matching the 1-2 pattern.Calculate Clearance Under Bridges & Cables.Estimated Position – Walk through step by step guide The description to this is fairly straightforward: whenever you see the pattern 1-2-2-1, it means theres two mines adjacent to the 2s, and the other two tiles will have no mine.Running Fix – Step by step guide & cheat sheet.Compass Variation and Deviation – how to calculate them.When a number touches the same number of squares, those squares must be mines. You also can play Custom games up to 30x24 with a minimum of 10 mines and maximum of (x-1)(y-1) mines. Minesweeper saves your best time for each difficulty level. A counter shows the number of mines without flags, and a clock shows your time in seconds. The game ends when all safe squares have been opened. The three difficulty levels are Beginner (8x8 or 9x9 with 10 mines), Intermediate (16x16 with 40 mines) and Expert (30x16 with 99 mines). This can save you a lot of work! However, if you place the correct number of flags on the wrong squares, chording will explode the mines. Chording is when you press both mouse buttons at the same time. If you flag all of the mines touching a number, chording on the number opens the remaining squares. A common strategy for starting games is to randomly click until you get a big opening with lots of numbers. When you open a square that does not touch any mines, it will be empty and the adjacent squares will automatically open in all directions until reaching squares that contain numbers. Pressing the right mouse button again changes your flag into a questionmark. You open squares with the left mouse button and put flags on mines with the right mouse button. Minesweeper and NP-completeness Minesweeper is NP-complete My original paper appeared under this title in the Spring 2000 issue of the Mathematical Intelligencer (volume 22 number 2, pages 9-15).

Windows Minesweeper always makes the first click safe. If you click on a mine you lose the game! You can use the number clues to solve the game by opening all of the safe squares. Safe squares have numbers telling you how many mines touch the square. Minesweeper is a game where mines are hidden in a grid of squares. Minesweeper on Windows XP with 40 mines solved in 28 seconds
