character(len=10) :: opt_strategy

This parameter determines the optimisation strategy used, where multiple strategies may be used for an algorithm, with differing costs in terms of memory usage or performance.

Possible values are:

• Speed - Use the optimisation strategy which maximises performance at the cost of additional memory usage.
• Default - Use the optimisation strategy that balances performance and memory usage.
• Memory - Use the optimisation strategy which minimises memory usage at a cost of decreased performance.

The use of this parameter is deprecated and will be phased out with time. The parameter opt_strategy_bias should be used instead.
