Description

Specifies a limit for the number of nonzero elements to read for an allocation of memory in a model with a quadratic matrix.

This parameter does not restrict the size of a problem. Rather, it indirectly specifies the default amount of memory that will be pre-allocated before a problem is read from a file. If the limit is exceeded, more memory is automatically allocated.

Values

Any integer from 0 to 268 435 450; default: 5 000.
