find_pomdp_solve {pomdpSolve}

Find the executable for 'pomdp-solve'

Description

Find the pomdp-solve executable to solve Partially Observable Decision Processes (POMDPs) (Kaelbling et al, 1998) installed by the pomdpSolve package.

Usage

find_pomdp_solve()

Details

This package only provides a direct interface to the executable. A more convenient and powerful interface is provided by the function pomdp::solve_POMDP() in package pomdp.

The executable of pomdp-solve in this direct interface needs to be called with system2() and runs in a separate process. This way, a failure in the solver will not compromise the R session. pomdp-solve creates files with the value function and the policy graph (see read_write).

Value

returns the path to the 'pomdp-solve' executable as a string or stops with an error.
