For most of the use cases, default configuration of Lc0 is good for use. If you have NVidia RTX GPU, you may want to change the default network to one of the larger ones.

Setting the parameters
All the engine parameters can be set using one of the following ways:
- Via UCI parameters
- Using command line flags
- With a config file.
UCI parameters
When an engine runs through a chess GUI, it communicates all the settings through the UCI protocol.
Time management
This page contains different types of time managers.
Time manager legacy
‘Legacy’ estimates and budgets time for a move based on ..to be documented
Time manager smooth
‘smooth’ estimates and budgets time for a move based on ..to be documented
Time manager Alphazero
This page contains an alternative time manager to be used by lczero.
Time manager alphazero
‘alphazero’ is an optional time manager simulating the time managent as was used by the AlphaZero project. ‘alphazero’ Makes the engine use AlphaZero time. The alphazero engine always budgeted 5 percent of total time left for the first upcoming move. Remaining time is divided by value alphazero-time-value. The Default value of 20 uses (all time / 20 = 5%) 5 percent of all remaining time. Lower values of ‘alphazero-time-value’ will spend more time in beginning of game, higher values will save more time for later in the game.
