Deep Hiarcs 14 Uci Chess Engine 35
the -i option has no effect in mcts mode, but in non-mcts mode the engine will stop when it reaches its first 10 ep x 10 ply, which is about 8.5 ply. this allows you to quickly check how far into a position the engine is.
one of the benefits of uci engines is that they often provide a faster pre-calculated analysis than is obtainable from a traditional uci engine with its main benefit being that it is much faster than the analysis is usually completed. other benefits of the uci protocol include being able to analyze many time controls in an efficient way, and being able to analyze on-line with new positions as they are being created. the uci protocol is also used by engines that do not support the stockfish engine protocol. this includes the junior engines and some of the iqn engines. the nolot protocol is also similar to the uci protocol, and is used by the noodle. these two protocols have been around for many years and are very robust.
the uci protocol is also known as the universal chess interface, and consists of four protocols: uci (universal chess interface), nolot, hiarcs, and mcts. these protocols have been around for many years, and have proven to be very robust. the hiarcs protocol is unique in that it is able to analyze positions as they are created. this is done by examining every ply in the position and then building a complete tree analysis for every position that occurs. this allows an engine to analyze positions as they are being created and can analyze on-line. the nolot protocol is also similar to the uci protocol, and is used by the noodle. this protocol is used by the noodle in the nolot test suite. the uci protocol is used by most of the top engines, including many of the chesscomputer.com engines.
the “variation limit” section allows the number of variations to be reduced by the engine. the default of 500 is more than sufficient. this limit can only be changed if the configuration file has been saved to disk. for most playing styles, 500 variations is more than enough. if you feel you need more variations and you are using a computer with a lot of memory, the default of 500 can be reduced to around 100 to keep the engine running in memory. the lower limit is set to 5 to allow the engine to search better if it needs to take longer to decide a position. if you set this to less than 5 the engine will check out more positions and if it finds a position that it can analyse faster than it can to set the position, it will prioritise the analysis first and when the engine has a position it can analyse then it will move the position into the transposition table (if the position has been marked as studied) and then analyse it and set it. it will then go back to searching the position and if it finds a position it can analyse quicker it will do so.
this is a bit of a strange one. it indicates the maximum number of moves the engine is allowed to make in the current position. the default is 500, which is more than enough most of the time. if you play longer games, at the higher levels, you may want to try changing this to 1000. this will not affect the playing strength of the engine as it does not use the moves in the position but it will allow more positions to be searched. the maximum allowed number of moves is limited to the available memory, even if you have a large memory system, so it is advisable to not change this if you do not have a lot of memory. this should be used with the variation limit setting to reduce the amount of time taken to analyse a position, but if you are running low on memory you can still reduce this limit to around 20. if you have less than 20 moves in the current position, the engine will just mark the position as a draw.
