After you have chosen the engine you want to analyse with you can also set the number of lines to analyse simultaneously. Normally HIARCS analyses with lines = 1 to find the best line of play from the current position, however you may be interested in the top N lines of play, if you are you can set the lines field to the number of lines you wish to see simultaneously computed. Please note having lines > 1 makes HIARCS significantly less efficient at finding the best move available- ie. it will take somewhat longer to reach the same depth of search.
The analysis output area is directly under the engine selector. The output area can show analysis in four |
main ways: |
1. |
Concise view showing only the best move( s) found so far along with the evaluation and depth of search |
2. |
History and Statistic view showing the history of analysis of this position with statistics |
3. |
Game Analysis progress showing the engine analysis progress as it analyses a game |
4. |
Endgame tablebase results showing the results of consulting huge endgame databases. |
The Analysis Explorer pane has 4 important shortcut icons next to the engine selector: Engine settings- this enables you to configure the engine options.
Start / stop analysing- if idle start analysing; if analysing, stop
View analysis history and statistics- toggle the view shown in the Analysis Explorer between a clean simple view and the history and statistics view.
Analyse
game- this icon button enables you to analyse the whole game with an engine.
Concise view
The concise view gives a very simple uncluttered view of the engine analysis in Analysis Explorer. The engine analysis is presented as Evaluation / Depth Principle-line
These data values are explained below:. 1. Evaluation in pawns. A positive value is in favour of White and shown in blue, a negative value is in favour of Black and shown in red. For example + 1.00 would indicate White is the equivalent of 1 pawn ahead. 2. Depth of search. This is the depth in half-moves or plies that the engine has searched to. The deeper an engine searches the better its analysis result usually is. 3. Principle line- This is the expected line of play the engine expects to occur with best play.
You can insert the evaluation, depth and best line of play into the Game Notation by simply clicking the blue evaluation and depth value. Here is an example where the above analysis has been added to the Game Notation pane:
